MC74HC Overview

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

MC74HC is a onsemi order-code family — not a single orderable MPN. This page lists 121 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.

Package: 16-SOIC (0.154", 3.90mm Width) | Mounting Type: Surface Mount | Supply Voltage: 2 V ~ 6 V | Logic Type: Binary Counter | Operating Temperature: -40°C ~ 85°C Other listed variants describe: NAND Gate IC, 4-Element, 2-IN CMOS, SOIC, 6V; Quad 2-Input NOR Gate, SOIC-14, CMOS, 6V.

Across listed variants, watch these parameters: packages: 16-SOIC (0.154", 3.90mm Width), 14-SOIC (0.154", 3.90mm Width), SC-74A, SOT-753.

Suffix examples in this family: 161ADG, 00ADR2G, 02ADR2G, 02ADR2G-Q, 02ADTR2G, 03ADR2G, 03ADTR2G, 04ADG. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.

Columns that actually vary on this page: Package Type. If two rows match on MPN prefix but differ there, they are not interchangeable for production.

Example MPNs: MC74HC161ADG, MC74HC00ADR2G, MC74HC02ADR2G, MC74HC02ADR2G-Q, MC74HC02ADTR2G, MC74HC03ADR2G.

Ordering Code Differences

How suffixes on MC74HC map to package, grade, and reel options.

MC74HC uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.

Suffixes seen here: 161ADG, 00ADR2G, 02ADR2G, 02ADR2G-Q, 02ADTR2G, 03ADR2G, 03ADTR2G, 04ADG, 05ADG, 05ADR2G (+111 more).

What changes between rows: Package Type. Sort the table by these columns when narrowing from base number to a single MPN.

Full MPN examples: MC74HC161ADG, MC74HC00ADR2G, MC74HC02ADR2G, MC74HC02ADR2G-Q, MC74HC02ADTR2G.

Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.

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.

Is MC74HC a single part I can order, or a family prefix?

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.

What do the suffix letters on MC74HC part numbers mean?

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.

Which specs actually differ between MC74HC variants here?

On this page the varying fields are: Package Type. Filter the table by the parameter you care about before picking an MPN.

Can I swap between 16-SOIC (0.154", 3.90mm Width), 14-SOIC (0.154", 3.90mm Width), SC-74A, SOT-753 packages in the same MC74HC family?

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.

What is the lifecycle status of MC74HC 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 MC74HC?

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.
