SN74HC423 DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATOR

The M54/74HC423/423A are high speed CMOS MONOSTABLE multivibrators fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. There are two trigger inputs, A INPUT (negative edge) and B INPUT (pos.
