TLC393IPWR

Comparators Overview

The TLC393IPWR is a dual micropower linear CMOS voltage comparator manufactured by Texas Instruments. It operates on a single supply voltage ranging from 3 V to 16 V with a typical quiescent current of 40 uA per device. The component features an open-drain output capable of sinking up to 6 mA, allowing flexible interfacing with various logic families. Key electrical specifications include a maximum input offset voltage of 5 mV and an input bias current as low as 1 pA. The device supports a wide operating temperature range from -40°C to +125°C and is housed in an 8-pin TSSOP package.

Comparators Feature Summary

• Dual-channel micropower linear CMOS architecture designed for low energy consumption applications
• Open-drain output stage providing compatibility with multiple logic levels and voltage domains
• High input impedance characteristics ensuring minimal loading on signal sources

Comparators Applications

• Battery-powered monitoring systems requiring ultra-low power standby states
• Threshold detection circuits in industrial control environments
• Over-voltage and under-voltage protection schemes

Comparators Procurement Notes

Verify the specific suffix IPWR indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required operating temperature range for the intended application environment. Cross-reference the datasheet revision history to validate parameter consistency against previous production batches.

Comparators Selection Notes

Select this component when dual comparators are needed within a constrained power budget. The open-drain output simplifies interface design with varying logic voltages without additional level shifting. Consider the 4.5 us response time for slower switching applications where speed is secondary to power efficiency. Evaluate the TSSOP-8 package dimensions against available PCB real estate constraints during layout planning.

Comparators Part Context

This part belongs to the TLC393 family of analog comparators, which are engineered for general-purpose use in low-power scenarios. The series distinguishes itself through CMOS technology that offers significantly lower power dissipation compared to bipolar counterparts. The TLC393IPWR specifically denotes the reel-packaged version of the standard TLC393IPW, facilitating automated assembly processes while maintaining identical electrical performance characteristics.

Comparators Replacement Considerations

The TLC393IPW serves as the tray-packaged equivalent with identical electrical specifications. Verify pinout compatibility if substituting with other dual comparator models from different manufacturers.
