TLC393CPW

Comparators Overview

The TLC393CPW is a dual micro-power voltage comparator from Texas Instruments, utilizing LinCMOS technology. It operates on a single supply voltage ranging from 2V to 36V or dual supplies of ±1V to ±18V. The device features two independent channels with open-drain outputs capable of sinking up to 8mA. Key electrical specifications include a typical input offset voltage of 5mV and a maximum quiescent current of 40µA per channel. It is housed in an 8-pin TSSOP package and supports a wide operating temperature range.

Comparators Feature Summary

• LinCMOS technology enables ultra-low power consumption suitable for battery-operated applications.
• Open-drain output structure allows flexible interfacing with various logic families via pull-up resistors.
• Wide single-supply voltage range accommodates diverse system power requirements without level shifting.

Comparators Applications

• Battery-powered monitoring systems requiring minimal standby current
• Threshold detection circuits for voltage level sensing
• Simple analog-to-digital conversion interfaces

Comparators Procurement Notes

Verify the specific suffix 'CW' against official Texas Instruments documentation to confirm the exact temperature grade and package variant. Ensure the ordering part number matches the required industrial or automotive qualification if applicable. Cross-reference the datasheet revision date to confirm pinout compatibility with existing designs.

Comparators Selection Notes

Select this component when low static current is critical compared to bipolar comparators. The open-drain output requires external pull-up resistors; ensure the resistor value balances speed and power dissipation. Verify that the input common-mode voltage range includes the signals being monitored, as it extends to the negative rail.

Comparators Part Context

This part belongs to the TLC393 family of dual micro-power comparators. It serves as a low-cost alternative to higher-speed comparators where propagation delay is not the primary constraint. The TSSOP-8 package offers a compact footprint for space-constrained printed circuit board layouts while maintaining thermal performance.

Comparators Replacement Considerations

Direct pin-compatible replacements include the LM393 series and other TLC393 variants with different suffixes indicating package or temperature changes. Verify that substitute parts maintain the same open-drain output configuration and input voltage limits to ensure circuit functionality remains unchanged.
