Overview
The TS393IDT is a micropower CMOS dual voltage comparator manufactured by STMicroelectronics. It features two independent comparators in an SOIC-8 surface-mount package. The device operates within a wide single supply range of 2.7 V to 16 V or dual supplies from ±1.35 V to ±8 V. Typical supply current is 9 μA per comparator, with a maximum operating supply current of 20 μA. Input bias current is typically 600 pA, and input offset voltage is 5 mV. The output type is CMOS with a maximum channel output current of 20 mA. Response time is 2.5 μs for a 5 mV overdrive. Operating temperature ranges from -40 °C to +125 °C.
Feature Summary
- Micropower CMOS technology providing extremely low consumption compared to bipolar equivalents
- Wide single supply voltage range supporting operation from 2.7 V to 16 V
- Input common-mode voltage range includes ground potential
- High input impedance characteristic typical of CMOS architecture
Applications
- Battery-powered systems requiring low quiescent current
- Voltage monitoring circuits
- Threshold detection applications
Procurement Notes
Verify the specific suffix IDT indicates the SOIC-8 package and reel/cut-tape packaging format as listed in distributor specifications. Confirm RoHS compliance status through official documentation before integration. Ensure design accounts for the specified thermal dissipation limits within the target operating temperature range of -40 °C to +125 °C.
Selection Notes
Select this component when pin-to-pin compatibility with the dual bipolar LM393 is required alongside significantly reduced power consumption. The CMOS output stage differs from open-drain outputs found in some legacy comparators; verify interface requirements. Consider the TS3702 if push-pull output functionality is preferred to eliminate external pull-up resistors while maintaining similar response times.
Part Context
This part belongs to the TS393 series of micropower dual voltage comparators. It serves as a low-power alternative to traditional bipolar comparators like the LM393. The series is designed for applications where power efficiency is critical without sacrificing the functional compatibility needed for direct replacement in existing designs.
Replacement Considerations
Public confirmed substitute part numbers include TS393DR2G from onsemi.
