Description
The Harris CD74HC32, CD74HCT32 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 74HCT logic family is functionally pin
compatible with the standard 74LS logic family.
