74AHC123APW

Dual retriggerable monostable multivibrator with reset

The 74AHC123A; 74AHCT123A is a dual retriggerable monostable multivibrator with reset. The basic output pulse width is programmed by selection of external components (REXT and CEXT). Once triggered this basic pulse width may be extended by retriggering either of the edge triggered inputs (nA or (nB). By repeating this process, the output pulse period (nQ = HIGH, nQ = LOW) can be made as long as desired. Alternatively, an output delay can be terminated at any time by a LOW-going edge on input nRD. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

Features and benefits

  • Wide supply voltage range from 2.0 V to 5.5 V

  • DC triggered from active HIGH or active LOW inputs

  • Retriggerable for very long pulses up to 100 % duty factor

  • Direct reset terminates output pulse

  • Overvoltage tolerant inputs to 5.5 V

  • All inputs have a Schmitt-trigger action

  • High noise immunity

  • Input levels:

    • For 74AHC123A: CMOS level

    • For 74AHCT123A: TTL level

  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level A

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Multiple package options

  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C

Sample

As a Nexperia customer you can order samples via our sales organization.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples. Check out the list of official distributors.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
