Interfacing to MM74HC High-Speed CMOS Logic

PublishTime：2022-02-07

This application note pertains to the VHC Speciality Function devices only (listed in this section of the databook).These devices are direct pin, function and spec replacements for their MM74HC counterparts.
On many occasions it might be necessary to interface MM74HC logic to other types of logic or to some other control circuitry. HC-CMOS can easily be interfaced to any other logic family including 74LS TTL, MM74C, CD4000 CMOS and 10,000 ECL logic. Logic interfacing can be sub-divided into two basic categories: interfacing circuitry operating at the same supply voltage and interfacing to circuitry operating on a different voltage. In the latter case, some logic level translation is usually required, but many easily available circuits simplify this task. Usually, both instances require little or no external circuitry
