74VHC221A Dual Non-Retriggerable Monostable Multivibrator April 1994 Revised May 1999 74VHC221A Dual Non-Retriggerable Monostable Multivibrator 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. Each multivibrator Features both a negative, A, and a positive, B, transition triggered input, either of which can be used as an inhibit input. Also included is a clear input that when taken LOW resets the one-shot. The VHC221A can be triggered on the positive transition of the clear...
