CD74HCT32 (ACTIVE) High Speed CMOS Logic Quad Two-Input OR Gates

High Speed CMOS Logic Quad Two-Input OR Gates - CD74HCT32
Datasheet
 

Description

The ’HC32 and ’HCT32 contain four 2-input OR gates in one package. 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.
