Pin and function compatible with 74HC123A
General Description
The VHC123A is an advanced high speed CMOS
Monostable Multivibrator fabricated with silicon gate
CMOS technology. It achieves the high speed operation
similar to equivalent Bipolar Schottky TTL while main-
taining the CMOS low power dissipation. Each multi-
vibrator features both a negative, A, and a positive, B,
transition 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 VHC123A can be
triggered on the positive transition of the clear while A is
held low and B is held high. The output pulse width is
determined by the equation: PW
= (R
x)(Cx); where PW
is in seconds, R is in ohms, and C is in farads.
Limits for Rx and Cx are:
External capacitor, Cx: No limit
External resistors, Rx:VCC = 2.0V, 5 kΩ min
VCC > 3.0V, 1 kΩ min
An input protection circuit ensures that 0 to 7V can be
applied to the input pins without regard to the supply
voltage. This device can be used to interface 5V to 3V
systems and two supply systems such as battery back
up. This circuit prevents device destruction due to mis-
matched supply and input voltages.
Ordering Information
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the
ordering number.
