TLC393CD

Comparators Overview

The TLC393CD is a dual micro-power voltage comparator from Texas Instruments, utilizing LinCMOS technology. It operates on a single supply ranging from 3 V to 16 V with a typical quiescent current of 50 µA. The device features an open-drain output capable of sinking up to 20 mA, allowing flexible interfacing with various logic families. It offers a propagation delay of 4.5 µs and a high common-mode rejection ratio of 84 dB. Designed for surface-mount applications, it is housed in an 8-SOIC package and supports an industrial operating temperature range of 0°C to 70°C.

Comparators Feature Summary

• LinCMOS architecture enables ultra-low power consumption suitable for battery-operated systems.
• Open-drain output structure provides compatibility with multiple logic voltage levels.
• High common-mode rejection ratio ensures stable performance against input noise.

Comparators Applications

• Battery-powered monitoring circuits
• Threshold detection systems
• General-purpose analog signal comparison

Comparators Procurement Notes

Verify the specific suffix 'CD' indicates the commercial temperature grade (0°C to 70°C) and SOIC-8 package configuration. Confirm RoHS compliance status through the official datasheet or manufacturer documentation prior to integration. Ensure the ordering part number matches the required tape-and-reel or tube packaging format specified by the supplier.

Comparators Selection Notes

Select this component when low static current is critical alongside moderate speed requirements. The open-drain output simplifies level shifting without additional components. Consider the 8-SOIC footprint for space-constrained PCB layouts. Verify that the 4.5 µs response time meets the system's timing constraints compared to faster alternatives.

Comparators Part Context

This device belongs to the TLC393 family of dual comparators. It shares functional similarities with the TLC193 but offers optimized power characteristics. The part is designed as a drop-in replacement for legacy dual comparator designs requiring reduced standby current while maintaining standard pinout compatibility.

Comparators Replacement Considerations

Direct substitutes include the TLC393CDR for reel-packaged equivalents. Other variants within the series such as the TLC393ID offer extended temperature ranges. Verify pinout compatibility before substituting with other dual comparator ICs.
