General Description
The VHC221A is an advanced high speed CMOS Monostable Multivibrator 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.
   
Features
■ High Speed: tPD = 8.1 ns (typ) at VCC = 5V
