CD4538BM/CD4538BC Dual Precision Monostable
General Description
The CD4538B is a dual, precision monostable multivibrator
with independent trigger and reset controls. The device is
retriggerable and resettable, and the control inputs are inter-
nally 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 deter-
mined by external components R
X
and C
X
. The device does
not allow the timing capacitor to discharge through the tim-
ing pin on power-down condition. For this reason, no exter-
nal protection resistor is required in series with the timing
pin. Input protection from static discharge is provided on all
pins.
