NXP Semiconductors CD74HCT
CD74HCT variants from NXP Semiconductors
CD74HCT 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.
- 2 distinct suffix patternsExamples: 4053PWRG4, 573DBR. 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 2 CD74HCT 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 |
|---|---|---|---|---|---|---|
| CD74HCT4053PWRG4 | IC MUX/DEMUX TRIPLE 2X1 16TSSOP | NXP Semiconductors | Active | Compliant | In Stock | |
| CD74HCT573DBR | Latch Transparent 3-ST 8-CH D-Type 20-Pin SO / IC LATCH OCTAL D 3STATE 20SOIC | NXP Semiconductors | Active | Compliant | In Stock |

How suffixes on CD74HCT map to package, grade, and reel options.
How to Choose the Right CD74HCT 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 CD74HCT, 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 "CD74HCT" — include the full suffix (e.g. 4053PWRG4, 573DBR). RFQ with reel/tube preference and required date code.
