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.
