TLC393CPWR

Comparators Overview

The TLC393CPWR is a dual low-power voltage comparator manufactured by Texas Instruments, utilizing LinCMOS technology. It operates on a single supply voltage ranging from 3 V to 16 V with a typical quiescent current of 40 µA. The device features an open-drain output configuration and offers a common-mode rejection ratio of 84 dB. Input bias current is specified at 5 pA, while the input offset voltage reaches a maximum of 5 mV. Propagation delay is typically 1.1 µs. It is housed in an 8-pin TSSOP package.

Comparators Feature Summary

• LinCMOS technology enables ultra-low power consumption suitable for battery-operated applications
• Open-drain output allows flexible interfacing with various logic families via external pull-up resistors
• Wide single-supply voltage range supports diverse system power architectures

Comparators Applications

• Voltage monitoring systems
• Threshold detection circuits
• Simple analog-to-digital conversion interfaces

Comparators Procurement Notes

Verify the specific suffix 'PWR' confirms the TSSOP-8 package and tape-and-reel packaging format. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before integration. Ensure the operating temperature range aligns with the commercial grade specifications defined in the technical data sheet.

Comparators Selection Notes

Select this component when low static current is critical compared to standard bipolar comparators. The open-drain output requires careful consideration of pull-up resistor values to meet speed and logic level requirements. Verify that the 1.1 µs propagation delay meets the timing constraints of the target application circuit.

Comparators Part Context

This part belongs to the TLC393 family of dual comparators, which are pin-compatible with industry-standard LM393 devices but offer improved power efficiency due to CMOS construction. The series is designed for general-purpose comparison tasks where power conservation is a primary design constraint.

Comparators Replacement Considerations

Direct pin-compatible replacements include the LM393N and LM393IDR. Verify that substitute components match the required package type and electrical characteristics such as input bias current and propagation delay.
