Features

Description

• Buffered Inputs

The Harris CD74HC20, CD74HCT20, 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 74HCT logic family is

functionally pin compatible with the standard 74LS logic

family.

• Typical Propagation Delay: 8ns at V

= 5V,
