TLV1824DR

Comparators Overview

The TLV1824DR is a quad-channel analog comparator from the Texas Instruments TLV182x family, housed in a 14-pin SOIC package. It features rail-to-rail inputs and open-drain outputs capable of being pulled 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 propagation delay of 420ns, an input offset voltage of ±3mV, and an input bias current of 150fA. It includes a Power-On Reset (POR) feature for known startup states.

Comparators Feature Summary

• Rail-to-rail input capability extending beyond supply rails
• Open-drain output stage supporting external pull-up voltages up to 40V
• Integrated Power-On Reset (POR) circuit for defined startup behavior
• Micro-power operation with low quiescent current consumption

Comparators Applications

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

Comparators Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the SOIC-14 package variant required for your PCB layout. Confirm that the open-drain output architecture aligns with your system's logic level requirements, as it necessitates an external pull-up resistor. Ensure the 40V maximum rating covers your highest expected signal or supply potential.

Comparators Selection Notes

Select this component when high-voltage tolerance and low power consumption are critical. The open-drain output is suitable for interfacing with different logic families via external pull-ups. Consider the TLV1814 if push-pull outputs are preferred to eliminate external resistors. Verify thermal dissipation requirements for the SOIC-14 package under your specific load conditions.

Comparators Part Context

This part belongs to the TLV18xx family of 40V rail-to-rail input comparators. The 'TLV182x' designation indicates the open-drain output option, distinguishing it from the TLV181x series which offers push-pull outputs. The 'Q1' suffix denotes automotive qualification, whereas the standard 'DR' suffix indicates commercial/industrial grade availability in the SOIC-14 package.

Comparators Replacement Considerations

The TLV1824PW (TSSOP-14) offers identical electrical characteristics in a different surface-mount package. For push-pull output functionality, the TLV1814 series serves as a functional alternative within the same family.
