M74HC123 DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATOR

The M74HC123 is an high speed CMOS c MONOSTABLE MULTIVIBRATOR fabricated with u silicon gate C2MOS technology. d There are two trigger inputs, A INPUT (negative ro edge) and B INPUT (positive edge). These inputs P are valid for slow rising/falling signals, (tr=tf=l sec). te The device may also be tr.
