74AHC139; 74AHCT139

Dual 2-to-4 line decoder/demultiplexer

The 74AHC139; 74AHCT139 decodes two binary weighted address inputs (nA0, nA1) to four mutually exclusive outputs (nY0 to nY3). Each decoder features an enable input (nE). When nE is HIGH all outputs are forced HIGH. The enable input can be used as the data input for a 1-to-4 demultiplexer application. 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 to 5.5 V

  • Balanced propagation delays

  • All inputs have Schmitt-trigger actions

  • High noise immunity

  • Overvoltage tolerant inputs to 5.5 V

  • Input levels:

    • For 74AHC139: CMOS level

    • For 74AHCT139: TTL level

  • CMOS low power dissipation

  • 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

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