DESCRIPTION
The M74HC123 is an high speed CMOS
MONOSTABLE MULTIVIBRATOR fabricated with
silicon gate C
2
MOS 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 approsimatively
given by the formula : tW(OUT) = K

.
Taking CLR low breaks this MONOSTABLE
STATE. If the next trigger pulse occurs during the
MONOSTABLE
period
MONOSTABLE period longer. Limit for values of
Cx and Rx : Cx : NO LIMIT
