TS339CPT

Overview

The TS339CPT is a micropower quad CMOS voltage comparator manufactured by STMicroelectronics. It features four independent comparators in a TSSOP-14 package, designed for low power consumption with a typical supply current of 20 µA per device. The component operates within a wide single supply range from 2.7 V to 16 V or dual supplies. Key electrical specifications include a response time of 1.5 µs, an input offset voltage (Vos) of 5 mV, and an input bias current (Ib) of 600 pA. The output type is open drain, capable of sourcing up to 20 mA per channel. It supports an operating temperature range from -40°C to +125°C.

Procurement Notes

Verify the specific suffix 'CPT' corresponds to the TSSOP-14 package and commercial grade temperature rating (-40°C to +85°C typically, though datasheet specifies -40°C to +125°C for the series). Confirm RoHS compliance status as indicated in official documentation. Ensure ordering quantities match available packaging options such as cut tape or reel sizes specified by the distributor. Cross-reference the manufacturer part number with the Mouser catalog entry 511-TS339CP for accurate identification.

Selection Notes

Select the TS339CPT when design requirements prioritize low power consumption alongside standard performance metrics comparable to bipolar LM339 devices. The TSSOP-14 package offers a compact surface-mount solution suitable for space-constrained PCB layouts. Consider this component for applications needing open-drain outputs that can interface with different voltage levels via external pull-up resistors. Evaluate the 5 mV input offset voltage specification against required accuracy thresholds for the specific analog signal conditioning task.

Part Context

The TS339CPT belongs to the TS339 family of micropower quad CMOS voltage comparators. This series is designed as a pin-to-pin and functionally compatible replacement for the bipolar LM339, offering significantly lower power consumption while maintaining similar response times. The TS339 series provides high input impedance and includes ground in the common-mode voltage range, making it versatile for single-supply applications. It is part of STMicroelectronics' broader portfolio of analog signal conditioning integrated circuits.
