74HC Family Complex Function, Texas Instruments

Texas Instruments range of Complex Function products from the 74HC High Speed CMOS Logic Family includes Binary Adders, Magnitude & Identity Comparators, Parity Checkers, 7-segment LCD Latch/Decoder/Drivers and PLL (Phase Locked Loop) ICs. The 74HC Family 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.
