TLV1393IDR

Comparators Overview

The TLV1393IDR is a dual low-power differential comparator manufactured by Texas Instruments. It operates within a supply voltage range of 1.8 V to 5.5 V and features rail-to-rail input and output capabilities. The device achieves a propagation delay of 40 ns with a quiescent current of 22 µA per channel. It is housed in an 8-pin SOIC package and supports an operating temperature range from -40°C to +125°C.

Comparators Feature Summary

• Rail-to-rail input and output functionality for maximum dynamic range
• Low power consumption with 22 µA quiescent current per channel
• High-speed performance with 40 ns propagation delay
• Wide single-supply operation from 1.8 V to 5.5 V

Comparators Applications

• Battery-powered portable devices requiring low standby current
• Threshold detection circuits in consumer electronics
• Signal conditioning in industrial control systems
• Temperature sensing interfaces

Comparators Procurement Notes

Verify the specific suffix 'IDR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the industrial temperature grade (-40°C to +125°C) meets the environmental specifications of the target application. Ensure compatibility with the 1.8 V to 5.5 V supply rails during system design validation.

Comparators Selection Notes

Select this component when both high speed and low power are critical constraints. The 40 ns delay offers faster response than standard comparators while maintaining microampere-level current draw. The rail-to-rail I/O simplifies interface design with logic families operating at varying voltage levels within the specified supply range.

Comparators Part Context

This part belongs to the TLV139x family of low-power comparators designed for modern battery-operated applications. It serves as a high-performance alternative to legacy bipolar comparators, offering significantly reduced power consumption without sacrificing switching speed. The device integrates CMOS input stages to minimize bias currents.

Comparators Replacement Considerations

Direct pin-compatible replacements include the LMV393IDR and TLV3501IDR, though electrical characteristics such as propagation delay and quiescent current differ. Verify that substitute components meet the specific 40 ns delay and 22 µA current requirements of the original design.
