Texas Instruments CD54HCT
CD54HCT variants from Texas Instruments
CD54HCT Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
CD54HCT is a Texas Instruments order-code family — not a single orderable MPN. This page lists 14 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.
High Speed CMOS Logic Hex Inverter 14-CDIP -55 to 125 Other listed variants describe: High Speed CMOS Logic Quad 2-Input AND Gates 14-CDIP -55 to 125; High Speed CMOS Logic Dual Positive-Edge Trigger J-K Flip-Flops with Set and Reset 16-CDIP -55 to 125.
Across listed variants, watch these parameters: packages: 14-CDIP (0.300", 7.62mm).
Suffix examples in this family: 04F, 08F3A, 109F3A, 138F, 157F3A, 163F3A, 245F, 257F3A. 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.
Example MPNs: CD54HCT04F, CD54HCT08F3A, CD54HCT109F3A, CD54HCT138F, CD54HCT157F3A, CD54HCT163F3A.
Key Features
- Footprint / package: 14-CDIP (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.
- 14 distinct suffix patternsExamples: 04F, 08F3A, 109F3A, 138F, 157F3A (+9 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — 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

Ordering Code Differences
How suffixes on CD54HCT map to package, grade, and reel options.
CD54HCT 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: 04F, 08F3A, 109F3A, 138F, 157F3A, 163F3A, 245F, 257F3A, 367F3A, 373F (+4 more).
Full MPN examples: CD54HCT04F, CD54HCT08F3A, CD54HCT109F3A, CD54HCT138F, CD54HCT157F3A.
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 CD54HCT Microcontrollers
Match the footprint first
Packages here: 14-CDIP (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 CD54HCT, 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 "CD54HCT" — include the full suffix (e.g. 04F, 08F3A, 109F3A). RFQ with reel/tube preference and required date code.
