MC14538B
Dual Precision
Retriggerable/Resettable
Monostable Multivibrator
The MC14538B is a dual, retriggerable, resettable monostable
multivibrator. It may be triggered from either edge of an input pulse,
and produces an accurate output pulse over a wide range of widths, the
duration and accuracy of which are determined by the external timing
components, C and R . Output Pulse Width T = R @ C (secs)

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.

ORDERING INFORMATION
See detailed ordering and shipping information in the package
dimensions section on page 2 of this data sheet.
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high−impedance circuit. For proper operation, V and V should be constrained
in
out
to the range V v (V or V ) v V
.

Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V or V ). Unused outputs must be left open.
