DESCRIPTION
The
M74HC423
is
an
high
speed
CMOS
MONOSTABLE MULTIVIBRATOR fabricated with
silicon gate C2MOS technology.
There are two trigger inputs, A INPUT (negative
edge) and B INPUT (positive edge). These inputs
are valid for slow rising/falling signals, (tr = tf = 1
sec). After triggering the output maintains the
MONOSTABLE
state
for
the
time
period
determined by the external resistor Rx and
capacitor Cx.
The pulse width constant is K
0.46.
Taking CLR low breaks this MONOSTABLE
STATE. If the next trigger pulse occurs during the
MONOSTABLE
period
it
makes
the
MONOSTABLE period longer. Limit for values of
Cx and Rx :
Cx : NO LIMIT
Rx : Vcc < 3.0V 5K to 1M
Vcc > 3.0V 1K to 1M
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
