74HC139; 74HCT139

Dual 2-to-4 line decoder/demultiplexer

The 74HC139; 74HCT139 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 include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Features and benefits

  • Input levels:

    • For 74HC139: CMOS level

    • For 74HCT139: TTL level

  • Demultiplexing capability

  • 2 independent 2-to-4 decoders

  • Multifunction capability

  • Suitable for memory decoding, data routing or code conversion

  • Complies with JEDEC standard no. 7A

  • Active LOW mutually exclusive outputs

  • 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
