MC74HC139A Datasheet Dual 1-of-4 Decoder/demultiplexer

Manufacturer: onsemi

Overview: Dual 1-of-4 Decoder/ Demultiplexer High−Performance Silicon−Gate CMOS MC74HC139A The MC74HC139A is identical in pinout to the LS139. The device inputs are patible with standard CMOS outputs; with pull−up resistors, they are patible with LSTTL outputs. This device consists of two independent 1−of−4 decoders, each of which decodes a two−bit Address to one−of−four active−low outputs. Active−low Selects are provided to facilitate the demultiplexing and cascading functions. The demultiplexing function is acplished by using the Address inputs to select the desired device output, and utilizing the Select as a data input.

Key Features

  • Output Drive Capability: 10 LSTTL Loads.
  • Outputs Directly Interface to CMOS, NMOS and TTL.
  • Operating Voltage Range: 2.0 to 6.0 V.
  • Low Input Current: 1.0 mA.
  • High Noise Immunity Characteristic of CMOS Devices.
  • In Compliance with the Requirements Defined by JEDEC Standard No. 7 A.
  • Chip Complexity: 100 FETs or 25 Equivalent Gates.
  • NLV Prefix for Automotive and Other.
