TS339IPT

Overview

The TS339IPT is a micro-power, CMOS, quad voltage comparator manufactured by STMicroelectronics. It features extremely low consumption of 9 μA typ./comparator and an input bias current of 1 pA typ. The device supports a wide single supply range from 2.7 V to 16 V or dual supplies (±1.35 V to ±8 V). It offers high input impedance of 10^12 Ω typ. and a fast response time of 1.5 μs typ. for 5 mV overdrive. The input common-mode voltage range includes ground. This component is pin-to-pin and functionally compatible with the bipolar LM339 device.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the requested quantity aligns with the manufacturer's minimum order requirements and lead times. Confirm RoHS compliance status if required for your assembly process. Cross-reference the part number with authorized distributors to validate authenticity and availability before finalizing procurement orders.

Selection Notes

Select this component when system design demands minimal power consumption alongside compatibility with existing LM339 footprints. It is suitable for applications requiring wide supply voltage flexibility and high input impedance. Consider the open-drain output configuration for interfacing with various logic families. Evaluate the propagation delay characteristics against signal speed requirements to ensure adequate performance margins in the target circuit topology.

Part Context

The TS339 belongs to STMicroelectronics' family of micro-power CMOS comparators. It serves as a low-power alternative to traditional bipolar comparators like the LM339. The device integrates four independent comparators within a single package, optimizing board space. Its CMOS technology enables operation at very low supply voltages while maintaining robust performance characteristics suitable for portable and battery-operated electronic devices.

Replacement Considerations

The TS339 is explicitly documented as pin-to-pin and functionally compatible with the bipolar LM339 device. Designers may substitute LM339 units with the TS339 to reduce power consumption without altering the physical layout. Verify that the open-drain output requirements are met by the new application circuitry.
