Glossary of Terms
 
4000 Series CMOS Technology
The 4000 series (also known as Metal Gate) is moving more slowly through its product life cycle than other technologies. This product features high voltage (up to 15 volts) and temperature tolerance and is extensively used in the automotive and industrial markets. Suppliers: Texas Instruments, ON Semiconductor, NXP, STMicroelectronics.

ABT - Advanced BiCMOS Technology
Advanced BiCMOS technology incorporates the speed of BiPolar with the power savings of CMOS. ABT will most likely replace other families like TTL as it continues to evolve. ABT is mostly used in high performance computing and communications equipment. Suppliers: Texas Instruments, NXP.

AC/ACT - Advanced CMOS
Advanced CMOS (AC/ACT) offers high-speed and ultra low power with guaranteed latch-up immunity. Advanced CMOS is a high-performance family found mostly in communications applications and computers. Suppliers: Texas Instruments, ON Semiconductor, STMicroelectronics.

AHC(T)/VHC(T) - Advanced (V) High CMOS
AHC(T)/VHC(T) is an enhanced version of the industry's High Speed CMOS (HC/T) family. This technology offers a cost-effective advantage with a performance upgrade including higher drive, faster speed and no noise penalty. AHC(T)/VHC(T) are identical on a pin for pin basis. This technology fits a broad range of applications such as computers, consumer, industrial, automotive, PC peripheral, portable and telecommunications. Suppliers: Texas Instruments, ON Semiconductor, NXP, STMicroelectronics.

ALS - Advanced Low Power Schottky
Delivers twice the data handling efficiency with up to 50% reduction in power consumption as compared with LS, making it the lowest power advanced TTL family. Supplier: Texas Instruments

AS - Advanced Schottky
Offers high switching speed with propagation delays of 4ns but consumes more power than standard TTL devices. Supplier: Texas Instruments

BCT - BiCMOS Technology
BCT is a family of 8,9 and 10-bit drivers, latches, transceivers and registered transceivers. Designed specifically for bus-interface applications, BCT offers TTL I/O with high speeds and very low power in the disabled mode. New products are now created in ABT technology.

CBT - Crossbar/Bus Switch
Crossbar Technology enables a bus-interface device to function as a very fast bus switch, isolating buses when the switch is open and offering very little delay when the switch is closed. Supplier: Texas Instruments

Clock Management
There is a broad range of clock drivers available to support voltage levels from 2.5V to 5.0V in both CMOS I/O and various differential I/O technologies. Clock drivers solve clock skew and clock multiplication/division issues. Many Phase Lock Loops (PLL's) used in SDRAM and PC motherboard applications require clock drivers. Clock drivers are found in telecom equipment, networking equipment, personal computers, work stations, main frame computers, printers, servers and PCI bus cards. Suppliers: STMicroelectronics, NXP, Texas Instruments and ON Semiconductor

ECL - Emitter Coupled Logic
ECL is a non-saturated form of digital logic that eliminates transistor storage time permitting very high speed operation. Suppliers: ON Semiconductor

FAST - Fast Advanced Schottky
FAST offers 20% to 30% improvement over standard Schottky (74S) with a 75% to 80% reduction in power. FAST is a state-of-the-art TTL family. Suppliers: NXP and Texas Instruments

FCT - Fast CMOS Technology
FCT includes a broad range of families with specific target applications. FCT provides high speed and very low power dissipation that is compatible in form, fit and function with standard logic families. Fast CMOS technology is found in a variety of applications including personal computers, network switches and routers, wireless telephony, memory modules, hand-held computers and set-top boxes. Suppliers: Texas Instruments

HC/HCT - High Speed CMOS High-speed CMOS
(HCMOS) delivers the low power, high noise immunity of CMOS at the speed performance of Low Power Schottky (LS) at a low price. Suppliers: ON Semiconductor, NXP, STMicroelectronics, Texas Instruments.

LCX, LVX, LVC, LVQ, LVT - Low Voltage Technology
In response to demand for portable systems, higher performance and lower operation voltages are required of standard logic. Many suppliers are now offering low voltage solutions. Each product family features unique operating characteristics and performance attributes optimized for specific low voltage applications. Suppliers: ON Semiconductor, NXP, STMicroelectronics, Texas Instruments.

LS - Low Power Schottky (TTL)
LS features a combined five-fold reduction in current and power when compared to standard TTL. Suppliers: ON Semiconductor and Texas Instruments

S - Schottky & 7400 TTL*
Schottky offers speeds twice as fast as LS but comes with the penalty of high power consumption. Supplier: Texas Instruments. TTL (74xxx) offers a combination of speed, power consumption, output source and sink capabilities suitable for most applications. Supplier: Texas Instruments
*There has been a decline in these devices as newer technologies are introduced. They are not recommended for new designs.

Single Gate
Single gate functions are the smallest packages available today. The packages are so small that they are only available on a reel. Single gates provide a simple solution for all market segments facing concerns about miniaturization, time to market and cost effectiveness. Common applications include computers, communication terminals and consumer products. All single gate devices are not pin-for-pin compatible. Suppliers: ON Semiconductor, NXP, STMicroelectronics, Texas Instruments.
