Description
The Harris CD74HC10, CD74HCT10, 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
Pinout
