intended to give the designer an alternative to LSTTL.

HSCMOS, with the faster speed advantage over

metal–gate CMOS (MC14000 series) and the lower power

consumption advantage over LSTTL, is an optimum choice

for midrange designs. With the availability of high–speed

CMOS microprocessors and memories, the ability to design

a 100% CMOS system is possible.

NMOS–to–CMOS interface problem. To achieve this

interface capability, some CMOS advantages had to be

compromised. These compromises include power

consumption, operating voltage range, and noise immunity.

TTL devices with significant advantages over the TTL

devices. However, in some cases, an equivalent HCT

device may not replace a TTL device without some form of

circuit modification.
