TLV1824DYYR

Comparators Overview

The TLV1824DYYR is a quad-channel analog comparator from the Texas Instruments TLV182x family, housed in a 14-pin SOT-23-THIN package. It features rail-to-rail inputs and open-drain outputs capable of pulling up to 40V independent of the supply voltage. The device operates on a wide supply range of 2.4V to 40V with a quiescent current of 5µA per channel. Key electrical parameters include a typical input offset voltage of 500µV, an input bias current of 150fA, and a propagation delay of 900ns (high-to-low) or 420ns (low-to-high). It includes a Power-On Reset feature and functions within a temperature range of -40°C to +125°C.

Comparators Feature Summary

• Rail-to-rail input capability allows operation across the full supply voltage range without phase inversion.
• Open-drain output stage enables logic level translation and connection to pull-up voltages up to 40V independent of the comparator supply.
• Integrated Power-On Reset ensures outputs remain in a known state during power-up and power-down sequences.
• Micro-power architecture provides low quiescent current consumption suitable for battery-operated applications.

Comparators Applications

• Appliances
• Factory automation and control
• Motor drives
• Infotainment and cluster systems

Comparators Procurement Notes

Verify the specific ordering suffix DYYR corresponds to the SOT-23-THIN-14 package configuration. Confirm that the open-drain output requirement aligns with system design needs for external pull-up resistors. Ensure the 40V maximum rating covers all potential signal and supply conditions in the target application environment.

Comparators Selection Notes

Select this component when high-voltage tolerance and low power consumption are required simultaneously. The open-drain output is distinct from the push-pull TLV181x variants; choose based on whether external pull-up flexibility is needed. Verify that the 500µV offset voltage meets precision requirements compared to higher-offset alternatives.

Comparators Part Context

This part belongs to the TLV181x/TLV182x family of 40V rail-to-rail input comparators. The TLV182x sub-series specifically utilizes open-drain outputs, whereas the TLV181x series offers push-pull outputs. Both share identical input characteristics and micro-power specifications, differing primarily in output drive topology and compatibility with external load configurations.

Comparators Replacement Considerations

Direct functional replacements within the same family include TLV1824DR (SOIC-14), TLV1824PW (TSSOP-14), and TLV1824RTE (WQFN-16). Automotive qualified equivalents are available as TLV1824QDRQ1 and TLV1824QPWRQ1. Ensure pinout compatibility and thermal performance match the existing PCB layout constraints.
