DC Electrical Characteristics of MM74HC High-Speed CMOS Logic

PublishTime：2022-02-07

The input and output characteristics of the MM74HC high-speed CMOS logic family were conceived to meet several basic goals. These goals are to provide input current and voltage requirements, noise immunity and quiescent power dissipation similar to CD4000 and MM74C metal-gate CMOS logic and output current drives similar to low power Schottky TTL. In addition, to enable merging of TTL and HC-CMOS designs, the MM74HCT sub family differs only in their input voltage requirements, which are the same as TTL,to ease interfacing between logic families.
In order to familiarize the user with the MM74HC logic family,its input and output characteristics are discussed in this application note, as well as how these characteristics are affected by various parameters such as power supply voltage and temperature. Also, for those users who have been designing with metalgate CMOS and TTL logic, notable differences and features of high-speed CMOS are compared to those logic families.
