TS393MDT

Overview

The TS393MDT is a micropower CMOS dual voltage comparator manufactured by STMicroelectronics. It features an SOIC-8 surface-mount package with two independent channels. The device operates on a single supply voltage ranging from 4 V to 16 V or dual supplies, consuming typically 20 uA of operating current. Key electrical parameters include an 800 ns response time, 5 mV input offset voltage, and 1 pA input bias current. It supports an open-drain output configuration and functions within a temperature range of -55 C to +125 C.

Feature Summary

• Micropower CMOS architecture providing extremely low power consumption compared to bipolar alternatives
• Wide single supply voltage range capability for flexible system integration
• Open-drain output structure allowing easy wired-OR connection and level shifting

Applications

• Battery-powered instrumentation circuits requiring minimal quiescent current
• Voltage monitoring systems utilizing wide supply ranges
• Signal conditioning stages in low-power analog front ends

Procurement Notes

Verify the specific suffix 'MDT' against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for SOIC-8 components. Cross-reference datasheet revisions to confirm parameter stability. Confirm end-of-life status if applicable to long-term production plans. Validate thermal dissipation limits under maximum load conditions.

Selection Notes

Select this component when ultra-low static current is critical for battery life extension. The CMOS technology offers higher input impedance than bipolar comparators like the LM393. Consider the open-drain output requirement for logic interface compatibility. Evaluate the 800 ns propagation delay against signal speed requirements. Verify that the extended industrial temperature range meets environmental constraints.

Part Context

The TS393 series represents STMicroelectronics' micropower CMOS comparator line, designed as a low-power alternative to traditional bipolar comparators. This family emphasizes reduced supply current while maintaining functional compatibility with industry-standard pinouts. The TS393MDT variant specifically denotes the surface-mount packaging configuration within this product family.

Replacement Considerations

The TS393IDT serves as a verified substitute within the same manufacturer's portfolio, offering similar micropower characteristics and SOIC-8 packaging. Both devices belong to the TS393 series and maintain functional equivalence for most design applications.
