74HCT161 Overview

What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).

Key Features

Footprint / package: 16-DIP (0.300", 7.62mm)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

Integrated Circuits (ICs) — 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 74HCT161 Integrated Circuits (ICs)

📦

Match the footprint first

Packages here: 16-DIP (0.300", 7.62mm). Open the land-pattern drawing before you substitute a different suffix.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For 74HCT161, 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 "74HCT161" — include the full suffix (e.g. complete order code). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the 74HCT161 product family.

Is 74HCT161 a single part I can order, or a family prefix?

74HCT161 currently maps to one listed MPN in our table. Still quote the complete part number on POs — some distributors strip suffixes in search results.

What do the suffix letters on 74HCT161 part numbers mean?

Suffix characters after 74HCT161 define package and grade. Compare the Package / Case and Operating Temp columns in the table, then verify against the manufacturer ordering guide.

What is the lifecycle status of 74HCT161 variants?

Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.

What should I send for an RFQ on 74HCT161?

Full manufacturer MPN (not just 74HCT161), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.
