TS393CDT

Overview

The TS393CDT 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 typical supply current of 9 μA per comparator and an input bias current of 1 pA typical. It provides a fast response time of 2.5 μs for a 5 mV overdrive. The output type is CMOS, with a maximum input offset voltage of 5 mV. It is housed in an SOIC-8 package and supports surface mount installation.

Feature Summary

• Micropower CMOS technology enabling extremely low consumption compared to bipolar alternatives
• Wide single and dual supply voltage operation ranges
• High input impedance with input common-mode voltage including ground
• Pin-to-pin and functionally compatible with the dual bipolar LM393

Applications

• Battery-powered systems requiring low power consumption
• Signal conditioning circuits utilizing window comparator configurations
• General-purpose analog signal comparison tasks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape specifications. Confirm RoHS compliance status through the latest datasheet revision. Ensure the SOIC-8 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that demand low quiescent current while maintaining performance comparable to standard bipolar comparators. The CMOS output stage requires consideration for pull-up resistor integration if open-drain behavior is needed. Verify that the operating temperature range of 0°C to +70°C aligns with the environmental conditions of the intended application.

Part Context

The TS393CDT belongs to the TS393 series of micropower CMOS dual voltage comparators. This series is designed as a low-power alternative to traditional bipolar comparators like the LM393. The device offers similar response times while significantly reducing power consumption, making it suitable for portable and battery-operated electronic designs.

Replacement Considerations

The TS393CDT is pin-to-pin and functionally compatible with the dual bipolar LM393. Designers may substitute the LM393 with this CMOS version to reduce power consumption without altering the circuit layout.
