TLC393IP

Comparators Overview

The TLC393IP is a dual micropower LinCMOS voltage comparator manufactured by Texas Instruments. It features an open-drain output configuration and operates on a single supply voltage ranging from 3 V to 16 V. The device draws a typical operating supply current of 40 uA, with a maximum input bias current of 5 pA at 5 V. It exhibits a propagation delay of 4.5 us and supports an output sink current of 6 mA per channel. The component is housed in an 8-PDIP package and functions within a temperature range of -40°C to +85°C.

Comparators Feature Summary

• LinCMOS technology enables ultra-low power consumption suitable for battery-operated applications.
• Open-drain outputs allow flexible interfacing with various logic families via external pull-up resistors.
• Wide single-supply voltage operation provides design versatility across different system architectures.

Comparators Applications

• Battery-powered monitoring systems requiring low quiescent current
• Threshold detection circuits for sensor signal conditioning
• General-purpose voltage level comparison in industrial control

Comparators Procurement Notes

Verify the specific suffix 'IP' confirms the 8-pin PDIP package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status as manufacturing processes evolve. Check for obsolescence notices or end-of-life declarations from Texas Instruments before finalizing procurement plans.

Comparators Selection Notes

Select this component when low static current is critical compared to bipolar comparators. Ensure the application requires open-drain outputs compatible with the intended logic levels. Verify that the 4.5 us response time meets the system's speed requirements, as faster alternatives exist in the family.

Comparators Part Context

This part belongs to the TLC393 series of dual micropower comparators. It shares functional similarities with the LM393 but utilizes CMOS technology for significantly reduced power dissipation. The 'I' designation indicates the industrial temperature range, distinguishing it from commercial variants like the TLC393C.

Comparators Replacement Considerations

TLC393IDR is listed as a manufacturer-recommended alternative. Verify pinout compatibility and electrical parameter equivalence before substitution. Consider package differences between DIP and SOIC formats during physical integration.
