Product Summary
The 74VHC221AMTCX 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. The 74VHC221AMTCX can be triggered on the positive transition of the clear while A is held LOW and B is held HIGH. The 74VHC221AMTCX is non-retriggerable, and therefore cannot be retriggered until the output pulse times out.
