HD74LV123A Datasheet Dual Retriggerable Monostable Multivibrators

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74LV123A Dual Retriggerable Monostable Multivibrators ADE-205-258A (Z) 2nd Edition June.

General Description

The HD74LV123A

Key Features

  • output pulse-duration control by three methods. In the first method, the A input is low and the B input goes high. In the second method, the B input is high and the A input goes low. In the third method, the A input is low, the B input is high, and the clear (CLR) input goes high. The basic pulse duration is programmed by selecting external resistance and capacitance values. The external timing capacitor must be connected between Cext and Rext/Cext (positive) and an external resistor connected b.
