High-speed CMOS (HCMOS) has dominated the logic marketplace over the past decade by delivering low power and low noise at a low price. With over 100 released devices, Texas Instruments is committed to being the last supplier of HCMOS. The HC family offers CMOS-compatible inputs and the HCT family offers TTL-compatible inputs.
While HCMOS can be used in most new designs, TI recommends Advanced High-speed CMOS (AHC) as your reliable and effortless migration path from the HC family. AHC delivers the same low noise as HC, with half the static power consumption of HC, at a competitive price. For more information, please refer to the AHC homepage.
