description/ordering information

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.

DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATORS

SCLS420G – JUNE 1998 – REVISED APRIL 2003

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, 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 ’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 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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. Voltage values are with respect to the network ground terminal.

2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

3. The package thermal impedance is calculated in accordance with JESD 51-7.

⁽¹⁾The marketing status values are defined as follows:

ACTIVE: Product device recommended for new designs.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in

a new design.

PREVIEW: Device has been announced but is not in production. Samples may or may not be available.

OBSOLETE: TI has discontinued the production of the device.

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.
