KK74VHC373 is an octal D-type latch with three-state outputs. It is designed for use in modern high-performance computers and electronic equipment for consumer applications. The high-level KK74VHC373 is identical in pinout to the IC series KK74HC373A, KK74HCT373A, KK74AC373A, KK74ACT373A. The input voltage levels are compatible with standard C-MOS levels. The output voltage levels are compatible with input levels of C-MOS, N-MOS, and TTL ICs.
The KK74VHC373 is an octal D‑type latch with three‑state outputs designed for use in high‑performance computers and consumer electronic equipment. It is pin‑compatible with the KK74HC373A, KK74HCT373A, KK74AC373A, and KK74ACT373A families and operates from a 2.0 V to 5.5 V supply.
The document lists detailed electrical parameters, including absolute maximum ratings, DC and AC characteristics, and timing diagrams for both input and output pulses. Package dimensions for both plastic DIP and SOIC versions are also provided.
