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.
