Data sheet acquired from Harris Semiconductor SCHS274 CD54HCT32, CD74HC32, CD74HCT32 High Speed CMOS Logic Quad 2-Input OR Gate 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.
