CD4538BC

Dual Precision Monostable

General Description

The CD4538BC is a dual, precision monostable multivibra-

tor with independent trigger and reset controls. The device

is retriggerable 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 lin-

ear CMOS techniques. The pulse duration and accuracy

are determined by external components R

device does not allow the timing capacitor to discharge

through the timing pin on power-down condition. 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.

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
