TND306 High-Speed CMOS Product Designation Definitions
Prepared by: Steve West ON Semiconductor http://onsemi.com
TECHNICAL NOTE
HC vs. HCT
ON Semiconductor’s High–Speed CMOS product family, 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. HCT devices offer a short–term solution to the TTL/ NMOS–to–CMOS interface problem. To achieve this interface capability, some CMOS advantages had to be compromised.
