Data sheet acquired from Harris Semiconductor

SCHS131C

High-Speed CMOS Logic

Dual 4-Input AND Gate

August 1997 - Revised September 2003

Features

Description

• Buffered Inputs

The ’HC21 and CD74HCT21 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: 9ns at V

= 5V,
