Description
The M74HC4538 is a high speed CMOS monostable
multivibrator fabricated with silicon gate C2MOS
technology.
Each multivibrator features both a negative A, and a
positive B, edge triggered input, either of which can be
used as an inhibit input. Also included is a clear input
that when taken low resets the one shot. The
monostable multivibrators are retriggerable. That is,
they may be triggered repeatedly while their outputs are
generating a pulse and the pulse will be extended.
Pulse width stability over a wide range of temperature
and supply is achieved using linear CMOS techniques.
The output pulse equation is simply: PW = 0.7 (R)(C)
where PW is in seconds, R in Omhs and C is in Farads.
All the inputs are equipped with protection circuits
against static discharge and transient excess voltage.
