FFF CompatibilityThe SN74F38DR uses the identical JEDEC standard 14-SOIC footprint and pinout layout as the 74F38SCX.Both parts share the same 14-SOIC package dimensions (0.154 in / 3.90 mm width) and mounting specifications.The SN74F38DR operates with the same 5V supply range, absolute maximum ratings, and 64 mA open-collector output sink current capability.The pinout and package are standard 14-SOIC, which mounts directly on the original land pattern.Identical package dimensions and mounting type (SMD).The ALS family consumes less power but is significantly slower (33 ns propagation delay vs 12.5 ns) and has a lower low-level output current rating (24 mA vs 64 mA).
AI Summary

74F38SCX by onsemi: NAND Gate IC 4 Channel Open Collector 14-SOIC.

The SN74F38DR is an active, direct drop-in replacement from Texas Instruments that matches the electrical performance, logic family speed, and physical footprint of the obsolete Fairchild part.

  • Direct drop-in pin-compatible replacement
  • Same FAST (F) logic family ensuring identical timing and propagation delay (12.5 ns)
  • Identical 64 mA low-level sink capability for high-current driving

The SN74ALS38BDR serves as an alternative from the Advanced Low-Power Schottky (ALS) family, which reduces system power consumption but operates with slower switching times and lower driver current.

  • Direct pin-compatible footprint in 14-SOIC
  • Significantly lower operating supply current compared to the FAST family
  • Highly reliable and widely available logic series
  • Slower propagation delay (33 ns vs 12.5 ns)
  • Lower low-level sink current (24 mA vs 64 mA)

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.

Frequently asked questions

Yes. The onsemi 74F38SCX is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
