TS339CD

Overview

The TS339CD is a micropower quad CMOS voltage comparator manufactured by STMicroelectronics. It 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 features an extremely low supply current of 9 μA per comparator and an input bias current of 1 pA typical. It provides a fast response time of 1.5 μs for a 5 mV overdrive. The component utilizes an SO14 plastic micropackage and includes open-drain outputs.

Feature Summary

• Extremely low power consumption with 9 μA typical supply current per comparator
• Wide operating voltage range supporting both single and dual supply configurations
• High input impedance with extremely low input bias and offset currents
• Functionally compatible with bipolar LM339 devices

Applications

• General purpose analog signal comparison
• Voltage level detection circuits
• Battery monitoring systems
• Temperature sensing interfaces

Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SO14 package configuration required for your design. Confirm that the industrial temperature grade meets your operational environment specifications. Ensure proper handling procedures are followed due to the CMOS input structure sensitivity. Cross-reference the datasheet revision date to ensure compatibility with your system requirements.

Selection Notes

Select this component when low power consumption is critical alongside standard comparator performance. It serves as a direct replacement for the bipolar LM339 in existing designs without requiring circuit modifications. Consider the SO14 package dimensions for PCB layout constraints. Evaluate the open-drain output requirement against your logic interface needs.

Part Context

This part belongs to the TS339 family of micropower comparators. It shares functional similarities with the TS3704, though the latter offers push-pull outputs. The TS339 series is designed to provide significant power savings compared to traditional bipolar comparators while maintaining comparable speed characteristics.

Replacement Considerations

The TS339CD is pin-to-pin and functionally compatible with the bipolar LM339 device.
