The TC74VHC123A/221A are high speed CMOS
MONOSTABLE MULTIVIBRATOR fabricated with silicon gate

MOS technology.
There are two trigger inputs,
A input (negative edge), and B
input (positive edge). These inputs are valid for a slow rise/fall
time signal (t
r
=
t
f
=
1 s) as they are schmitt trigger inputs. This
device may also be triggered by using
CLR
input (positive
edge).
After triggering, the output stays in a MONOSTABLE state for
a time period determined by the external resistor and capacitor
(R
X
, C
X
). A low level at the
CLR
input breaks this state.
Limits for C

An input protection circuit ensures that 0 to 5.5 V can be
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5 V to 3 V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
