Dual Monostable Multivibrator

MONOSTABLE MULTIVIBRATOR fabricated with silicon gate

input (positive edge). These inputs are valid for a slow rise/fall

time signal (t

device may also be triggered by using CLR input (positive

edge).

a time period determined by the external resistor and capacitor

applied to the input pins without regard to the supply voltage.

This device can be used to interface 5 V to 3 V systems and two

supply systems such as battery back up. This circuit prevents

device destruction due to mismatched supply and input voltages.
