TECHNICAL DATA
Dual Monostable Multivibrator
High-Voltage Silicon-Gate CMOS
The IW4528B 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
