74HCT Family Complex Function, Texas Instruments
Texas Instruments Complex Function ICs from the 74HCT CMOS Logic Family includes Binary Adders, Magnitude & Identity Comparators, PLLs (Phase Locked Loop) and 4-to-7 BCD Decoder/Drivers. Inputs of the 74HCT family are 74LSTTL compatible, and the products use silicon gate CMOS technology to achieve operating speeds similar to the LSTTL family but with the low power consumption of standard CMOS integrated circuits.
High-Speed CMOS Logic
Operating Voltage 4.5 to 5.5 V
Compatibility: Input TTL, Output CMOS
