Overview
The TS331CX5 RFG is a single precision voltage comparator from Taiwan Semiconductor, housed in an SOT-25 package. It supports wide single-supply operation from 2V to 36V and split-supply ranges of ±1V to ±18V. Key electrical parameters include a typical input offset voltage of 2mV (max 5mV), low input bias current of 25nA, and supply current drain of 0.4mA at 5V. The device features an open-drain output capable of sinking up to 20mA, with a large signal response time of 300ns. It operates within a temperature range of -40°C to +105°C.
Feature Summary
- Low input offset voltage of ±2mV typ for high precision applications
- Wide single-supply voltage range from 2V to 36V
- Input common mode range extends to ground level
- Output compatible with DTL, ECL, TTL, MOS, and CMOS logic levels
Applications
- Consumer automotive electronics
- Industrial electronics
- Zero crossing detection circuits
- Time delay generation
- Square-wave oscillators
Procurement Notes
Verify the specific ordering suffix RFG corresponds to the 3Kpcs / 7” Reel packing configuration as listed in the official datasheet. Confirm that the component meets halogen-free requirements if indicated by the marking code. Ensure the supplier provides documentation matching the B14 version specifications. Cross-reference the manufacturer part number TS331CX5 RFG with authorized distribution channels to guarantee authenticity and traceability.
Selection Notes
Select this comparator when high precision is required due to its low input offset voltage specification. It is suitable for designs requiring wide supply voltage flexibility, supporting both single and split supplies. The low input bias current minimizes loading effects on source circuits. Consider the SOT-25 package size for space-constrained PCB layouts. Ensure the application does not require rail-to-rail output swing, as this device utilizes an open-drain output structure.
Part Context
The TS331CX5 RFG belongs to the TS331 series of low power, low offset voltage comparators manufactured by Taiwan Semiconductor. This series is designed for general-purpose comparison tasks in consumer and industrial environments. The component integrates PNP transistor inputs, allowing the common mode voltage to reach ground potential. It is distinct from higher-speed or rail-to-rail output variants available in the broader comparator market.
Replacement Considerations
Direct pin-compatible replacements should be verified against the SOT-25 footprint and electrical characteristics. Check for equivalent input offset voltage, supply current, and output sink capabilities. Ensure any substitute supports the required 36V maximum supply voltage and maintains similar response times.
