Overview
The TS339IN is a micropower quad CMOS voltage comparator manufactured by STMicroelectronics. It features an extremely low supply current of 9 μA typical per comparator, which is significantly lower than bipolar equivalents. The device operates on a wide single supply range from 2.7 V to 16 V or dual supplies from ±1.35 V to ±8 V. It exhibits extremely low input bias and offset currents of 1 pA typical. The input common-mode voltage range includes ground, and the device offers high input impedance of 10^12 Ω typical. Response time is fast at 1.5 μs typical for 5 mV overdrive. It is pin-to-pin and functionally compatible with the bipolar LM339.
Feature Summary
- Micropower CMOS technology providing extremely low consumption
- Wide single and dual supply voltage operation ranges
- Extremely low input bias and offset currents
- Pin-to-pin and functionally compatible with bipolar LM339
Applications
- Signal conditioning circuits
- Voltage monitoring systems
- Threshold detection applications
Procurement Notes
Verify the specific order code TS339IN corresponds to the DIP14 package and industrial temperature range (-40 °C to +125 °C). Confirm that the component is in full production status as indicated in the datasheet. Ensure compatibility with existing PCB footprints designed for standard plastic DIP packages. Check for any updated environmental compliance specifications such as ECOPACK grades before finalizing procurement.
Selection Notes
Select this component when replacing bipolar comparators like the LM339 to achieve significant power savings without sacrificing performance. It is suitable for battery-powered applications due to its low quiescent current. Consider the open-drain output type and ensure appropriate pull-up resistors are included in the design. Verify that the operating voltage range fits within the specified 2.7 V to 16 V limits for single supply configurations.
Part Context
The TS339 series consists of micropower quad CMOS voltage comparators designed to offer similar performance to bipolar devices while consuming much less power. The TS339IN specifically denotes the industrial grade version housed in a 14-pin Dual In-line Package (DIP14). This part is part of a broader family that includes variants with different packaging options such as SO14 and TSSOP14, catering to various integration needs.
Replacement Considerations
Direct replacement for bipolar LM339 devices due to functional and pin compatibility. Ensure circuit designs accommodate the CMOS input characteristics and open-drain outputs.
