Field-programmable gate arrays (FPGAs) have a different architecture than SPLDs and CPLDs, and typically offer higher capacities. FPGAs are also known as logic cell arrays (LCA) and programmable ASIC (pASIC).

Logic Adders

(29 companies)
Logic adders are digital devices that are capable of adding binary numbers. There are two basic types: half-adders and full-adders.

Logic Comparators

(41 companies)
Digital comparators are circuits used to compare the magnitude of two binary quantities and to determine the relationship of those quantities.

Shift Registers

(52 companies)
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.
Arithmetic logic units (ALU) perform arithmetic and logic operations on binary data inputs. In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU).

Logic Counters

(77 companies)
Logic counters are integrated circuits used for counting events in computers and other digital systems.

Panic Bars

(54 companies)
Panic Bars are door opening devices that span emergency exit doors on its interior. They open the latch when pressure is applied.

Magnetic Locks

(24 companies)
Magnetic locks are devices that secure door or gate entryways by using magnetic force. Current is supplied to electromagnets to hold or cut off, allowing the door or gate to be opened. These devices are used in commercial applications as well as industry. several output lines. Logic decoders and logic demultiplexers are integrated circuits (ICs) that move data between inputs and outputs. Logic decoders convert coded information into a familiar or uncoded form so that, for example, binary coded decimal...
Silicon controlled rectifiers (SCR) are four-layer (PNPN) thyristors with three terminals: an input control terminal (gate), an output terminal (anode), and a terminal common to both the input and output (cathode). SCRs are used mainly with high voltages and currents, often to control alternating current (AC) where the change of sign causes the device to switch off automatically.

Valve Repair Machines

(12 companies)
Valve repair machines are used to machine valve seats and faces on gate, globe, check, ball, safety, and control valves. Portable, or in-line, machines are used for on-site repairs (primarily grinding and lapping) while the valve is on-site or still in-line. Stationary machines are for off-line valve repair.
Complex programmable logic devices (CPLDs) are integrated circuits (ICs) or chips that application designers configure to implement digital hardware such as mobile phones. CPLDs can handle significantly larger designs than simple programmable logic devices (SPLDs), but provide less logic than field programmable gate arrays (FPGAs).

Logic Dividers

(38 companies)
...technologies such as Fairchild advanced Schottky TTL (FAST) use transistors as digital switches. By contrast, emitter coupled logic (ECL) uses transistors to steer current through gates that compute logical functions. Another logic family...

Door Operators

(179 companies)
Door operators are devices used to open and close all types of doors or gates. These operators can be powered by a variety of power sources such as electric, hydraulic or pneumatic devices.


(336 companies)
Like all thyristors, Shockley diodes tend to stay on once they have been turned on (latched), and stay off once they have been turned off. There are two ways to latch a Shockley diode: exceed the anode-to-cathode breakover voltage, or exceed...
