Description
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.
