Texas Instruments SNJ54ABT
SNJ54ABT variants from Texas Instruments
SNJ54ABT Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 4 distinct suffix patternsExamples: 125W, 373J, 374J, 541J. 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 Variants
Compare 4 SNJ54ABT part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|
| SNJ54ABT125W | Quadruple Bus Buffer Gates With 3- State Outputs 14-CFP -55 to 125 | Texas Instruments | Active | Compliant | In Stock | |
| SNJ54ABT373J | Octal Transparent D-type Latches With 3-State Outputs 20-CDIP -55 to 125 | Texas Instruments | Active | Compliant | In Stock | |
| SNJ54ABT374J | Octal Edge-Triggered D-Type Flip-Flops with 3-State Outputs 20-CDIP -55 to 125 | Texas Instruments | Active | Compliant | In Stock | |
| SNJ54ABT541J | Military 8-ch, 4.5-V to 5.5-V buffers with TTL-compatible CMOS inputs and 3-state outputs 20-CDIP -55 to 125 | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right SNJ54ABT Microcontrollers
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For SNJ54ABT, 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 "SNJ54ABT" — include the full suffix (e.g. 125W, 373J, 374J). RFQ with reel/tube preference and required date code.
