DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATORS

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
The variance in output pulse duration from device to device is typically less than
±0.5% for given external timing
components. An example of this distribution for the ’AHCT123A is shown in Figure 10. Variations in output pulse
duration versus supply voltage and temperature are shown in Figure 6.
During power up, Q outputs are in the high state, and Q outputs are in the low state. The outputs are glitch free
without applying a reset pulse.
The SN54AHCT123A is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74AHCT123A 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.
