General Specifications
   Logic Family       
   Your choices are...         
   Transistor-Transistor Logic (TTL)       Transistor-transistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT), diodes and resistors. It is notable, as it was the base for the first widespread semiconductor integrated circuit (IC) technology. All TTL circuits operate with a 5 V power supply. TTL signals are defined as "low" or L when between 0 V and 0.8 V with respect to the ground terminal, and "high" or H when between 2 V and 5 V. The first logic devices designed from bipolar transistors were referred to as standard TTL. The addition of Schottky diodes to the base collector of bipolar transistor was called Schottky logic (S-TTL). Schottky diodes shorten propagation delays within TTL by preventing the collector from going into what is called “deep saturation.”  Other TTL technologies include low-power Schottky (LS-TTL), advanced Schottky (AS-TTL), advanced low-power Schottky (ALS-TTL), and low-voltage TTL (LVTTL). 
   Standard CMOS       Complementary metal-oxide semiconductor (CMOS) logic uses a combination of p-type and n-type metal-oxide-semiconductor field effect transistors (MOSFET) to implement logic gates and other digital circuits found in computers, telecommunications and signal processing equipment. It is the technology of choice for many present-day digital integrated circuits. CMOS 4000 refers to the series 4000 that is true CMOS with non-TTL levels. 
   Low Voltage CMOS       There are several low voltage CMOS technologies: standard low voltage (LV), low voltage high performance HCMOS (LVC), low voltage CMOS technology with TTL inputs (LVT), Low voltage with TTL inputs and high impedance (LVTC), advanced low voltage CMOS with bus hold (ALVCH), low voltage CMOS that operates with 3 V or 5 V (LCX), and low voltage CMOS that operates with 1.8 V or 3.6 V (VCX). 
   BiCMOS       BiCMOS is a SiGe Bipolar technology that combines the high speed of bipolar TTL with the low power consumption of CMOS. There are a number of BiCMOS flavors including advanced BiCMOS technology (ABT), advanced BiCMOS technology with enhanced transceiver logic (ABTE), advanced low-voltage BiCMOS (ALB), advanced low-voltage BiCMOS technology (ALVT), BiCMOS with TTL inputs (BCT), BiCMOS with backplane and transceiver logic (BTL), and low-voltage BiCMOS technology (LVT). 
   Emitter Coupled Logic (ECL)       Emitter coupled logic (ECL) uses transistors to steer current through gates that compute logical functions. By comparison, TTL and related families use transistors as digital switches, where the transistors are either cut off or saturated, depending on the state of the circuit. This distinction explains ECL's chief advantage: that because the transistors are always in the active region, they can change state very rapidly, so ECL circuits can operate at very high speed; and also its major disadvantage: the transistors are continually drawing current, which means the circuits require high power, and thus generate large amounts of waste heat. ECL gates use differential amplifier configurations at the input stage. A bias configuration supplies a constant voltage at the midrange of the low and high logic levels to the differential amplifier, so that the appropriate logical function of the input voltages will control the amplifier and the base of the output transistor. The propagation time for this arrangement can be less than a nanosecond. Other noteworthy characteristics of the ECL family include the fact that the large current requirement is approximately constant, and does not depend significantly on the state of the circuit. This means that ECL circuits generate relatively little power noise, unlike many other logic types that typically draw far more current when switching than quiescent, for which power noise can become problematic. ECL circuits operate with negative power supplies, and logic levels incompatible with other families, which means that interoperation between ECL and other designs are difficult. The fact that the high and low logic levels are relatively close mean that ECL suffers from small noise margins, which can be troublesome in some circumstances.

   Package       
   Your choices are...         
   BGA       Ball-grid array (BGA) places output pins in a solder ball matrix. Generally, BGA traces are fabricated on laminated (BT-based) substrates or polyimide-based films. Therefore, the entire area of substrates or films can be used to route the interconnection. BGA has another advantage of lower ground or power inductance by assigning ground or power nets via a shorter current path to PCB. Thermally enhanced mechanisms (heat sink, thermal balls, etc.) can be applied to BGA to reduce the thermal resistance. The sophisticated capabilities make BGA the desirable package to implement electrical and thermal enhancement in response to the need for high power and high speed ICs. 
   CSP       Chip scale package or chip size package (CSP) has an area that is no more than 20% larger than the built-in die. CSP is compact for second level packaging efficiency and encapsulated for second level reliability. CSP is superior to both direct-chip-attach (DCA) and chip-on-board (COB) technologies. CSP is used in a variety of integrated circuits (IC), including radio frequency ICs (RFIC), memory ICs, and communication ICs.   
   DIP       Dual in-line package (DIP) is a type of semiconductor component packaging. DIPs can be installed either in sockets or permanently soldered into holes extending into the surface of the printed circuit board. The pins are distributed into two parallel lines along opposite site of the rectangular package. There are several types of DIP packages, such as Ceramic Dual in-line package (CDIP), Plastic Dual in-line package (PDIP), and Shrink Plastic Dual in-line package (SPDIP). 
   QFP       Quad flat packages (QFP) contain a large number of fine, flexible, gull wing shaped leads. Lead width can be as small as 0.16 mm. Lead pitch is 0.4 mm. QFPs provide good second-level reliability and are used in processors, controllers, ASICs, DSPs, gate arrays, logic, memory ICs, PC chipsets, and other applications.   
   LQFP       Low quad flat package (LQFP). 
   TQFP       Thin quad flat package (TQFP).
