The TC74VHC273 is an advanced high speed CMOS OCTAL D-TYPE FLIP FLOP fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
The TC74VHC273F/FT/FK is a high‑speed CMOS octal D‑type flip‑flop with clear, offering TTL‑like performance with low power dissipation. It is pin‑compatible with the 74ALS273 and includes features such as balanced propagation delays, wide operating voltage range (2‑5.5 V), and power‑down protection on all inputs.
