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.
