Overview
The TSX339IPT is a micropower CMOS quad voltage comparator manufactured by STMicroelectronics. It features an open-drain output and operates within a wide single supply range of 2.7 V to 16 V, or dual supplies from ±1.35 V to ±8 V. The device exhibits a typical supply current of 5 µA per comparator and an extremely low input bias current of 1 pA typ. It provides fast response times, typically 2 µs for a 5 mV overdrive, and includes high ESD tolerance rated at 4 kV HBM and 200 V MM. The component is housed in a TSSOP14 package.
Feature Summary
- Micropower operation with very low current consumption of 5 µA typical per comparator
- High input impedance with extremely low input bias current of 1 pA typical
- Enhanced electrostatic discharge (ESD) protection capabilities
- Pin-to-pin and functionally compatible with the TS339 series
Applications
- Automotive systems
- Industrial applications
Procurement Notes
Verify that the specific order code matches the required package type and temperature range. Confirm that the 'I' suffix indicates the industrial temperature grade (-40 °C to 125 °C). Ensure compatibility with existing designs referencing the TS339 family. Check for any specific environmental compliance requirements such as ECOPACK grades before finalizing procurement.
Selection Notes
Select this component when low power consumption is critical alongside standard comparator functionality. It serves as a direct replacement for the TS339 with improved offset voltage and ESD performance. Consider the TSSOP14 package for space-constrained PCB layouts requiring surface-mount technology. Verify that the open-drain output configuration aligns with the system's logic level requirements.
Part Context
The TSX339 belongs to the micropower quad CMOS voltage comparator family from STMicroelectronics. It was designed as an improvement over the legacy TS339 model, offering lower current consumption and better input offset voltage characteristics. The product line supports various packages including SO14, TSSOP14, and QFN16 3x3 to accommodate different integration needs.
Replacement Considerations
The TSX339 is fully compatible with the TS339 CMOS comparator. Designers can replace TS339 units with the TSX339 without modifying the circuit layout due to pin-to-pin compatibility.
