These edge-triggered multivibrators feature
output pulse-duration control by three methods. In
the first method, the A input is low, and the B input
goes high. In the second method, the B input is
high, and the A input goes low. In the third method,
the A input is low, the B input is high, and the clear
(CLR) input goes high.

description/ordering information (continued)
The output pulse duration is programmed by selecting external resistance and capacitance values. The external
timing capacitor must be connected between Cext and Rext/Cext (positive) and an external resistor connected
between Rext/Cext and VCC. To obtain variable pulse durations, connect an external variable resistance between
Rext/Cext and VCC. The output pulse duration also can be reduced by taking CLR low.
Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input
pulse. The A, B, and CLR inputs have Schmitt triggers with sufficient hysteresis to handle slow input transition
rates with jitter-free triggering at the outputs.
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. CLR input can be used to override
A or B inputs. 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 ’AHC123A 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 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.

APPLICATION INFORMATION
caution in use
To prevent malfunctions due to noise, connect a high-frequency capacitor between VCC and GND, and keep
the wiring between the external components and Cext and Rext/Cext terminals as short as possible.
power-down considerations
Large values of Cext can cause problems when powering down the ’AHC123A devices because of the amount
of energy stored in the capacitor. When a system containing this device is powered down, the capacitor can
discharge from VCC through the protection diodes at pin 2 or pin 14. Current through the input protection diodes
must be limited to 30 mA; therefore, the turn-off time of the VCC power supply must not be faster than
t = VCC × Cext/30 mA. For example, if VCC = 5 V and Cext = 15 pF, the VCC supply must turn off no faster than
t = (5 V) × (15 pF)/30 mA = 2.5 ns. Usually, this is not a problem because power supplies are heavily filtered
and cannot discharge at this rate. When a more rapid decrease of VCC to zero occurs, the ’AHC123A devices
can sustain damage. To avoid this possibility, use external clamping diodes.
output pulse duration
The output pulse duration, tw, is determined primarily by the values of the external capacitance (CT) and timing
resistance (RT). The timing components are connected as shown in Figure 2.

if CT is ≥1000 pF, K = 1.0 or

APPLICATION INFORMATION
retriggering data
The minimum input retriggering time (tMIR) is the minimum time required after the initial signal before retriggering
the input. After tMIR, the device retriggers the output. Experimentally, it also can be shown that to retrigger the
output pulse, the two adjacent input signals should be tMIR apart, where tMIR = 0.30 × tw. The retrigger pulse
duration is calculated as shown in Figure 3.
tMIR
Input
tRT = tw + tPLH = (K × RT × CT) + tPLH

Output
Where:
tMIR = Minimum Input Retriggering Time
tPLH = Propagation Delay
tRT = Retrigger Time
tw
= Output Pulse Duration Before Retriggering
Figure 3. Retrigger Pulse Duration
The minimum value from the end of the input pulse to the beginning of the retriggered output should be
approximately 15 ns to ensure a retriggered output (see Figure 4).

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)
