FFF CompatibilityThe part is functionally and physically identical, sharing the exact same package and pinout.Identical physical dimensions and mounting footprint.The 'E4' suffix designates TI's standard lead-free/RoHS formulation (NiPdAu plating) of the same underlying silicon; there are no functional differences.Both parts use the standard 16-pin PDIP package and share the identical pinout configuration.Both devices are in the identical 16-PDIP package with compatible dimensions and mounting styles.The SN74HC139AN is an updated "A" version of the dual 2-to-4 line decoder/demultiplexer that meets or exceeds all electrical and timing specifications of the original SN74HC139N.
AI Summary

SN74HC139N by Texas Instruments: Decoder/Demultiplexer 1 x 2:4 16-PDIP.

The SN74HC139NE4 is an identical replacement to the SN74HC139N, carrying the TI-specific 'E4' suffix to denote lead-free/RoHS-compliant NiPdAu lead plating.

  • Identical device to the source part with standard lead-free/RoHS-compliant NiPdAu lead finish (E4 suffix)
  • Exact same electrical, timing, and thermal performance
  • Direct drop-in replacement with no layout or electrical changes required

The SN74HC139AN is a fully compatible, direct drop-in replacement. It offers slightly improved propagation delay times while keeping the identical pinout, operating conditions, and package.

  • Direct pin-to-pin drop-in replacement in the same 16-PDIP package
  • Slightly faster propagation delays (max 33 ns vs 44 ns at 4.5V over temperature)
  • Identical operating voltage range (2 V to 6 V) and temperature range (-40°C to 85°C)

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
