MC14528B

Dual Monostable

Multivibrator

The MC14528B is a dual, retriggerable, resettable monostable

multivibrator. It may be triggered from either edge of an input pulse,

and produces an output pulse over a wide range of widths, the duration

of which is determined by the external timing components, C

X

and

R

X

.

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

in

and V

out

should be constrained

to the range V

SS

(V

in

or V

.

Unused inputs must always be tied to an appropriate logic voltage level (e.g.,

either V

SS

or V

). Unused outputs must be left open.
