MC74HC Overview

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

Key Features

  • Footprint / package: 16-SOIC (0.154", 3.90mm Width), 14-SOIC (0.154", 3.90mm Width), SC-74A, SOT-753Land pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
  • Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
  • 121 distinct suffix patternsExamples: 161ADG, 00ADR2G, 02ADR2G, 02ADR2G-Q, 02ADTR2G (+116 more). Decode suffix meaning in the ordering notes under the variant table.

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 MC74HC Integrated Circuits (ICs)

📦

Match the footprint first

Packages here: 16-SOIC (0.154", 3.90mm Width), 14-SOIC (0.154", 3.90mm Width), SC-74A, SOT-753. Open the land-pattern drawing before you substitute a different suffix.

Electrical headroom

Compare voltage and current columns in the variant table. For MC74HC, 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 "MC74HC" — include the full suffix (e.g. 161ADG, 00ADR2G, 02ADR2G). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the MC74HC product family.

MC74HC is a base / family code from onsemi. You order a full MPN such as MC74HC161ADG, MC74HC00ADR2G, MC74HC02ADR2G. The variant table lists 121 orderable lines with different suffixes.
Listed suffix fragments include: 161ADG, 00ADR2G, 02ADR2G, 02ADR2G-Q, 02ADTR2G, 03ADR2G. Typically they encode package (16-SOIC (0.154", 3.90mm Width), 14-SOIC (0.154", 3.90mm Width), SC-74A, SOT-753), temperature grade, and tape/reel option. Always decode on the onsemi datasheet ordering guide — do not guess from pattern alone.
On this page the varying fields are: Package Type. Filter the table by the parameter you care about before picking an MPN.
Only after footprint and thermal review. Packages listed here (16-SOIC (0.154", 3.90mm Width), 14-SOIC (0.154", 3.90mm Width), SC-74A, SOT-753) use different land patterns and often different thermal resistance. Layout swaps need a new paste stencil at minimum, not just a BOM edit.
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.
Full manufacturer MPN (not just MC74HC), 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.
Use the datasheet link in the page header. Cross-check electrical curves (SOA, saturation voltage, etc.) against your operating point — the table summarizes order codes, not every graph in the PDF.
