74HC137PW

3-to-8 line decoder, demultiplexer with address latches; inverting

The 74HC137 decodes three binary weighted address inputs (A0, A1 and A2) to eight mutually exclusive outputs (Y0 to Y7). The device features a latch enable (LE) and two output enable (E1, E2) inputs. A LOW on LE causes the device to act as an active LOW decoder. A LOW-to HIGH transition on LE stores the data that was present before the transition in the latches. Further address changes are ignored as long as LE remains HIGH.

The output enable inputs control the state of the outputs independently of the address inputs or latch operation. All outputs will be HIGH unless E1 is LOW and E2 is HIGH.

Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Features and benefits

  • Combines 3-to-8 decoder with 3-bit latch

  • Multiple input enable for easy expansion or independent controls

  • Active LOW mutually exclusive outputs

  • Wide supply voltage range from 2.0 to 6.0 V

  • CMOS low power dissipation

  • High noise immunity

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

  • Complies with JEDEC standards

    • JESD8C (2.7 V to 3.6 V)

    • JESD7A (2.0 V to 6.0 V)

  • ESD protection:

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

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

  • Specified from -40 °C to +80 °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.
