74LVC139

Dual 2-to-4 line decoder/demultiplexer

The 74LVC139 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 can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

Features and benefits

  • Wide supply voltage range from 1.2 V to 3.6 V

  • Overvoltage tolerant inputs to 5.5 V

  • CMOS low power dissipation

  • Direct interface with TTL levels

  • Demultiplexing capability

  • Two independent 2-to-4 decoders

  • Multifunction capability

  • Mutually exclusive outputs

  • Output drive capability 50 Ω transmission lines at 125 °C

  • Complies with JEDEC standard:

    • JESD8-7A (1.65 V to 1.95 V)

    • JESD8-5A (2.3 V to 2.7 V)

    • JESD8-C/JESD36 (2.7 V to 3.6 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

  • Multiple package options

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