CD4538BC

Dual Precision Monostable

General Description

Features

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_Xand C_X. The

■ Wide supply voltage range: 3.0V to 15V

■ High noise immunity: 0.45 V_CC(typ.)

■ Low power TTL compatibility:

Fan out of 2 driving 74L or 1 driving 74LS

■ New formula:

PW_OUT= RC (PW in seconds, R in Ohms, C in Farads)

■ ±1.0% pulse-width variation from part to part (typ.)

■ Wide pulse-width range: 1 µs to ∞

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.

■ Separate latched reset inputs

■ Symmetrical output sink and source capability

■ Low standby current: 5 nA (typ.) @ 5 V_DC

■ Pin compatible to CD4528BC
