CD4538 - Dual Precision Monostable Multivibrator IC

The CD4538 IC is a dual, precision monostable multivibrator with independent trigger and reset controls. The device is re-triggerable and resettable, and the control inputs are internally latched. Two trigger inputs are provided to allow either rising or falling edge triggering. The reset inputs are active low and prevent triggering while active. Precise control of output pulse-width has been achieved using linear CMOS techniques.

The pulse duration and accuracy are determined by external components RX and CX. The device does not allow the timing capacitor to discharge through the timing pin on power-down conditions. For this reason, no external protection resistor is required in series with the timing pin. Input protection from static discharge is provided on all pins.
