Features

Description

• Buffered Inputs

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.

• Typical Propagation Delay: 8ns at V

= 5V,
