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 cir-

cuits. All devices have the ability to drive 10 LSTTL loads.

The HCT logic family is functionally pin compatible with the

standard LS logic family.
