TLV7021DBVR

Comparators Overview

The TLV7021DBVR is a single-channel, low-voltage comparator manufactured by Texas Instruments. It features a rail-to-rail input capability and operates within a supply voltage range of 1.6 V to 5.5 V. The device provides an open-drain output and includes internal hysteresis of 14 mV to prevent oscillation during threshold transitions. Key electrical specifications include a typical propagation delay of 260 ns and a maximum static supply current of 10 µA. It supports input offset voltages up to 8 mV at 5 V and maintains high common-mode rejection and power supply rejection ratios of 78 dB. The component is housed in a surface-mount SOT-23-5 package.

Comparators Feature Summary

• Rail-to-rail input functionality allows operation across the full supply voltage range.
• Internal hysteresis eliminates noise-induced output fluctuations without external components.
• Open-drain output stage enables flexible logic level translation and wired-OR configurations.

Comparators Applications

• Threshold detection and signal discrimination circuits
• Zero-crossing detectors for AC signal processing
• Window comparator implementations

Comparators Procurement Notes

Verify the specific suffix DBVR corresponds to the SOT-23-5 package and tape-and-reel orientation before ordering. Confirm that the open-drain output architecture aligns with the pull-up requirements of the target system interface. Ensure the operating temperature range meets the environmental conditions of the final assembly.

Comparators Selection Notes

Select this component when space-constrained designs require a micro-power comparator with integrated hysteresis. The open-drain output is suitable for interfacing with different logic families via external pull-ups. Consider the 260 ns propagation delay for timing-sensitive applications requiring fast response to input changes.

Comparators Part Context

This part belongs to the TLV7011/TLV7021 family of low-voltage comparators designed for portable and battery-powered applications. While the TLV7011 offers a push-pull output, the TLV7021 variant specifically provides an open-drain configuration. Both share identical input characteristics and low power consumption profiles.
