74HC Family

74HC Family Inverters & Buffers, Texas Instruments

Texas Instruments range of Inverters and Buffers from the 74HC Family of CMOS Logic 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.

High-Speed CMOS Logic
Operating Voltage: 2 to 6 V
Compatibility: Input CMOS, Output CMOS

74LS Family

74LS Family Inverters & Buffers, Texas Instruments

Texas Instruments range of Inverters and Buffers from the 74LS Family of Low Power Schottky Logic ICs. The 74LS Family use bipolar junction technology coupled with Schottky diode clamps to achieve operating speeds equal to the original 74TTL family but with much lower power consumption.
