IDT54AHCT139 Datasheet High Speed CMOS Dual 1-of-4 Decoder

Manufacturer: IDT

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

: The IDTS4174AHCT139 are dual 1-of-4 decoders built using advanced CEMOS'·, a dual metal CMOS technology.

The device has two independent decoders, each of which accept two binary weighed inputs (Ao-A 1) and provides four mutually exclusive active LOW outputs (0 0-0 3), Each decoder has an active LOW enable (E).

When E is HIGH, all outputs are forced HIGH.

Key Features

  • Equivalent to ALS speeds and output drive over full temperature and voltage supply extremes.
  • 9ns typical address to output delay.
  • IOL = 14mA over full military temperature range.
  • CMOS power levels (5p. W typo static).
  • Both CMOS and TTL output compatible.
  • Substantially lower input current levels than ALS (Sp. A max. ).
  • DuaI1-of-4 decoder with enable.
  • 100% product assurance screening to MIL-STD-883, Class B is available.
