74LVC1G123

Single retriggerable monostable multivibrator;

Schmitt trigger inputs

Rev. 7 — 20 April 2021

Product data sheet

1. General description

The 74LVC1G123 is a single retriggerable monostable multivibrator with Schmitt trigger inputs.

Output pulse width is controlled by three methods:

1. The basic pulse is programmed by selection of an external resistor (R_EXT) and capacitor (C_EXT).

2. Once triggered, the basic output pulse width may be extended by retriggering the gated active

LOW-going edge input (A) or the active HIGH-going edge input (B). By repeating this process,

the output pulse period (Q = HIGH) can be made as long as desired. Alternatively an output

delay can be terminated at any time by a LOW-going edge on input CLR, which also inhibits the

triggering.

3. An internal connection from CLR to the input gates makes it possible to trigger the circuit by a

HIGH-going signal at input CLR.

Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices

as translators in a mixed 3.3 V and 5 V environment. Schmitt trigger inputs, makes the circuit highly

tolerant to slower input rise and fall times.

This device is fully specified for partial power-down applications using I_OFF. The I_OFFcircuitry

disables the output, preventing the damaging backflow current through the device when it is

powered down.
