74LV123

Dual retriggerable monostable multivibrator with reset

Rev. 8 — 4 March 2016

Product data sheet

1. General description

The 74LV123 is a low-voltage Si-gate CMOS device and is pin and function compatible

with the 74HC123; 74HCT123. It is a dual retriggerable monostable multivibrator which

uses three methods to control the output pulse width:

1. The basic pulse time is programmed by the selection of an external resistor (R

EXT

)

and capacitor (C

EXT

). These are normally connected as shown in

Figure 9.

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

gated active LOW-going edge input (nA) or the active HIGH-going edge input (nB). By

repeating this process, the output pulse period (nQ = HIGH, nQ = LOW) can be made

as long as desired (see

Figure 12).

3. Alternatively, an output delay can be terminated at any time by a LOW-going edge on

input nRD, which also inhibits the triggering (see

Figure 13).

Schmitt-trigger action in the nA and nB inputs makes the circuit highly tolerant of slower

input rise and fall times.

2. Features and benefits



Optimized for low-voltage applications: 1.0 V to 5.5 V

Accepts TTL input levels between V

= 2.7 V and V

= 3.6 V

Typical output ground bounce: < 0.8 V at V

= 3.3 V and T

amb

= 25

C

Typical HIGH-level output voltage (V

) undershoot: > 2 V at V

= 3.3 V and

amb

= 25

C

DC triggered from active HIGH or active LOW inputs

Retriggerable for very long pulses up to 100 % duty factor

Direct reset terminates output pulses

Schmitt-trigger action on all inputs except for the reset input
