TC74HC423AP Datasheet (Toshiba) - Dual Retriggerable Monostable Multivibrator

TC74HC423AP, Dual Retriggerable Monostable Multivibrator

(1) Stand-by state The external capacitor Cx is fully charged to VCC in the stand-by state.

That means, before triggering, the QP and QN transistors which are connected to the Rx/Cx node are in the off state.

Two comparators that relate to the timing of the output pulse, and two reference voltage su

TC74HC423AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC423AP, TC74HC423AF Dual Retriggerable Monostable Multivibrator The TC74HC423A is a high speed CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS technology.

It achieves 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 (positive edge).

These inputs are valid for a slow rise/fall time
