Search other suppliers in the following categories:
Active filters are electronic filers that use active components such as voltage amplifiers or operational amplifiers. The amplifier shapes and stabilizes the behavior of the filter, and serves as a buffer interface to the driven component.
Amplifier and comparator chips are board-level components for amplifying voltage, current, or power.
Analog comparators are amplifiers that compare the magnitude of voltages at two inputs. An analog comparator is an operational amplifier with negative feedback removed, and with no feedback and very high gain, the output voltage goes to one extreme to the other.
Battery charger ICs are integrated circuits (IC) that are used to charge batteries.
Digital counters are integrated circuits used for counting events in computers and other digital systems.
Digital decoders and digital demultiplexers move data between inputs and outputs. In the case of digital decoders, the coded information is translated into familiar or uncoded formats, while digital multiplexers transmit data from one input through to several output lines. 
Digital dividers are integrated circuits that divide the frequency of an input signal by a divisor value.
Digital latches are logic devices that latch onto or retain digital states (1 or 0) in data storage circuits.
Digital parallel and serial converters change input streams of parallel data into output streams of serial bits, or vice versa.
Flip-flops are digital logic devices that synchronize changes in output state (1 or 0) according to a clocked input.
Gate drivers are electronic circuits that apply correct power levels to metal-oxide field-effect transistors (MOSFETs) and insulated gate bipolar transistors (IGBTs).
IC analog crosspoint switches are used for routing high speed signals such as video and audio signals.
Analog multiplexers have sets of switches that connect several analog inputs to a common analog output, allowing a single analog-to-digital converter (ADC) to sample data from multiple inputs.
IC bus interfaces and controllers or bus masters are interfaces between most standard parallel-bus microcontrollers or microprocessors and the serial bus.
IC drivers or gate drivers provide the current and voltage necessary to turn power switching elements such as MOSFETs or IGBTs either on or off, based on the logic output signals of a DSP, micro-controller or other logic device.
IC electronic filters are frequency-selective circuits that consist of devices such resistors, capacitors, inductors, transistors, or operational amplifiers coupled with reactive components.
IC interfaces are semiconductor chips that are used to control and manage the sharing of information between devices.
Integrated circuit (IC) linear voltage regulators use voltage-controlled sources to force a fixed voltage to appear at their output terminal.
IC phase-locked loops (PLL) are closed-loop frequency controls that are based on the phase difference between the input signal and the output signal of a controlled oscillator.
IC switching voltage regulators are integrated circuits (ICs) that store energy in an inductor, transformer, or capacitor and then use this storage device to transfer energy from the input to the output in discrete packets over a low-resistance switch.
IC timers are semiconductor circuits that generate or set timing for electronics circuits.
IC voltage regulators are three-terminal devices that provide a constant DC output voltage that is independent of the input voltage, output load current, and temperature. IC voltage regulators are used in power supplies that hold their output voltage constant over a wide range of load variations.
Laser drivers control and manage the operation of lasers used for switching in optical networks.
LED drivers control the amount of current and voltage supplied to light emitting diodes (LEDs), when in operation.
Logic gates are electronic circuits that combine digital signals according to boolean algebra.
Logic level translators adapt or convert one voltage or logic level to another.
Microcontrollers (MCU) are complete computer systems on a chip. They combine an arithmetic logic unit (ALU), memory, timer/counters, serial port, input/output (I/O) ports and a clock oscillator.
Network and communication chips are semiconductor integrated circuits (IC) used in telecommunication devices and systems.
Network equipment is used to split, switch, boost, or direct packets of information along a network. This product area includes network hubs, switches, routers, bridges, gateways, multiplexers, transceivers and firewalls. Often, network equipment is defined by is protocol or port type (e.g., Ethernet switch, USB hub).
Network media converters change the signal of encoded data from one media type to another as it is transmitted through, or between, networks.
Network switches route packets between ports at the OSI layer 2, which means that (in Ethernet) the switches decide where incoming packets are transferred to, based on the NIC's 48-bit address.
Operational amplifiers (op amps, op-amps) are general-purpose, closed-loop devices that are used to implement linear functions.
Power over Ethernet (PoE) controllers are used to control the delivery of DC power and data from power source equipment (PSE) to powered devices (PD).
Power over Ethernet (PoE) products use network cables to deliver DC power and data to network devices. PoE products use RJ connectors instead of AC-DC adapters and eliminate the need for separate power cables.
Programmable logic devices (PLD) are designed with configurable logic and flip-flops linked together with programmable interconnect. PLDs provide specific functions, including device-to-device interfacing, data communication, signal processing, data display, timing and control operations, and almost every other function a system must perform.
RF and wireless chips are integrated circuits (IC) that are designed specifically for radio frequency (RF), microwave, and other wireless communications or data transmission applications.
Semiconductor foundry services suppliers design and manufacture semiconductor chips on a contract basis, in prototype to production quantities.
Serializer/de-serializer (SERDES) macro-cell circuits receive fast serial signals (on the order of Mbits/s or higher) and de-serialize them into slower parallel signals. Some SERDES circuits can be programmed like any other PLD.
Shift registers are sequential logic circuits that are used to store and move data. They accept binary inputs from one serial or parallel source and then shift the data through a chain of flip-flops, one bit at time.
Specialty communications and wireless chips are specialty or proprietary products and accessories related to communications, wireless and telecommunications chip products.
Specialty IC interface devices are specialty or proprietary products related to IC interface devices.
Supervisory circuits and battery monitor chips are semiconductor devices that detect and monitor voltage levels in power supplies, microprocessors, and other systems.
Voltage references are electronic circuits that produce a constant output voltage (reference) that is used to compare other voltages in a system.
