description/ordering information(continued)
Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input
pulse. The A
rates with jitter-free triggering at the outputs.
, B, and CLR inputs have Schmitt triggers with sufficient hysteresis to handle slow input transition
Once triggered, the basic pulse duration can be extended by retriggering the gated low-level-active (A
high-level-active (B) input. Pulse duration can be reduced by taking CLR
A
or B inputs. The input/output timing diagram illustrates pulse control by retriggering the inputs and early
low. CLR input can be used to override
) or
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 ’AHCT123A is shown in Figure 10. V ariations in output pulse
duration versus supply voltage and temperature are shown in Figure 6.
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.
For additional application information on multivibrators, see the application report, Designing With the
SN74AHC123A and SN74AHCT123A, literature number SCLA014.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.
