Texas Instruments PCA9536DGKR
PCA9536DGKR variants from Texas Instruments
PCA9536DGKR Overview
What changes between part numbers, and what to check before you lock the BOM — I/O Expanders.
Key Features
- Footprint / package: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)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.
Target Applications
- I/O Expanders — 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 PCA9536DGKR part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| PCA9536DGKR | Package: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) | Mounting Type: Surface Mount | Supply Voltage: 2.3V ~ 5.5V | Interface: I²C, SMBus | Operating Temperature: -40°C ~ 85°C | 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) | Texas Instruments | Active | Compliant | In Stock | |
| PCA9536DGKRG4 | Package: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) | Mounting Type: Surface Mount | Supply Voltage: 2.3V ~ 5.5V | Interface: I²C, SMBus | Operating Temperature: -40°C ~ 85°C | 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right PCA9536DGKR I/O Expanders
Match the footprint first
Packages here: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For PCA9536DGKR, 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 "PCA9536DGKR" — include the full suffix (e.g. G4). RFQ with reel/tube preference and required date code.
