Overview
The TS393ID is a micropower CMOS dual 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 typically 9 µA per comparator and high input impedance of 10^12 Ω typical. Input common-mode voltage includes ground, with typical input bias and offset currents of 1 pA. Response time is typically 2.5 µs for 5 mV overdrive. It is housed in an SO-8 plastic micropackage and supports an industrial temperature range of -40 °C to +125 °C.
Feature Summary
- Pin-to-pin and functionally compatible with the dual bipolar LM393
- Extremely low power consumption suitable for battery-operated applications
- High input impedance with input common-mode voltage including ground
Applications
- Battery-powered systems requiring low quiescent current
- Signal conditioning circuits
- Window comparator configurations
Procurement Notes
Verify that the specific order code matches the required temperature grade and package type. Confirm the presence of the 'I' suffix indicates the industrial temperature range (-40 °C to +125 °C). Ensure the 'D' suffix corresponds to the SO-8 package variant. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions before finalizing procurement specifications.
Selection Notes
Select this component when pin compatibility with the LM393 is required alongside significantly lower power consumption. Consider the TS3702 if a push-pull output stage eliminating external pull-up resistors is preferred. Verify that the open-collector output architecture aligns with the system's logic level requirements and pull-up resistor availability.
Part Context
The TS393 series represents a micropower CMOS alternative to traditional bipolar comparators. It offers similar performance metrics while consuming approximately 20 times less current than the dual bipolar LM393. This family allows designers to maintain response times comparable to legacy devices while achieving substantial energy savings in portable and low-power electronic designs.
Replacement Considerations
The TS393ID is functionally compatible with the LM393. For push-pull output requirements, the TS3702 serves as a direct functional equivalent.
