description (continued)
Once triggered, the basic pulse duration can be extended by retriggering the gated low-level-active (A) or
high-level-active (B) input. Pulse duration can be reduced by taking CLR low. The input/output timing diagram
illustrates pulse control by retriggering the inputs and early clearing.
The variance in output pulse duration from device to device typically is less than
±0.5% for given external timing
components. An example of this distribution for the ’LV123A is shown in Figure 11. Variations in output pulse
width versus supply voltage and temperature are shown in Figure 7.
During power up, Q outputs are in the low state, and Q outputs are in the high state. The outputs are glitch free,
without applying a reset pulse.
Pin assignments for these devices are identical to those of the ’AHC123A and ’AHCT123A devices for
interchangeability when allowed.
The SN54LV123A is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74LV123A is characterized for operation from –40
°C to 85°C.
For additional application information on multivibrators, see the application report
Designing With the
SN74AHC123A and SN74AHCT123A, literature number SCLA014.

These outputs are based on the
assumption
that
the
indicated
steady-state conditions at the A and
B inputs have been set up long enough to
complete any pulse started before the
setup.
