The ’HC02 and ’HCT02 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.
