CD74HCT20 - High Speed CMOS Logic Dual 4-Input NAND Gates

Updated : 2020-01-09 14:38:28
Description

The ’HC20 and ’HCT20 logic gates utilize silicon gate CMOS technology to achieve operating speeds similar to LSTTL gates with the low power consumption of standard CMOS integrated circuits. All devices have the ability to drive 10 LSTTL loads. The HCT logic family is functionally pin compatible with the standard LS logic family.
