ON MC14528B Dual monostable multivibrator Datasheet

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, CX and
RX.

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, Vin and Vout should be constrained
to the range VSS
(Vin or Vout)
VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either VSS or VDD). Unused outputs must be left open.
