NXP Semiconductors 74HC138
74HC138 variants from NXP Semiconductors
74HC138 Overview
What changes between part numbers, and what to check before you lock the BOM — Analog Switches, Multiplexers and Demultiplexers.
Key Features
- Footprint / package: 16-SOIC (0.154", 3.90mm Width)Single package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
Target Applications
- Analog Switches, Multiplexers and Demultiplexers — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

How to Choose the Right 74HC138 Analog Switches, Multiplexers and Demultiplexers
Match the footprint first
Packages here: 16-SOIC (0.154", 3.90mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For 74HC138, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "74HC138" — include the full suffix (e.g. D/S200118). RFQ with reel/tube preference and required date code.
