The VHC273 is an advanced high speed CMOS Octal D-type flip-flop fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
The 74VHC273 is a high‑speed CMOS octal D‑type flip‑flop offering up to 165 MHz operation at a 5 V supply while consuming only a few microamps of quiescent current. It features pin‑compatible functionality with the 74HC273 family and includes power‑down protection on all inputs.
