2 Description
The ’HC4002 logic gate utilizes 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 ’HC4002 logic
family is functional as well as pin compatible with the
standard LS logic family.
