DESCRIPTION
The
M54HC123
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=l sec).
The device may also be triggered by using the
CLR
input
(positive-edge)
because
of
the
Schmitt-trigger input; after triggering the output
maintains the MONOSTABLE state for the time
period determined by the external resistor RX and
capacitor CX. When CX > 10nF and RX > 10K,
the output pulse width value is approximately
given by the formula: tW(OUT) = K Cx Rx.
(K
0.45).
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.
