TLV1391IDBVT

Comparators Overview

The TLV1391IDBVT is a single-channel differential analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 7 V and draws a typical quiescent current of 150 µA. The device features an open-collector output capable of sourcing 20 mA. Key electrical specifications include a maximum input offset voltage of 5 mV, an input bias current of 400 nA, and a response time of 180 ns. It is housed in a SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Comparators Feature Summary

• Differential input configuration for precise signal comparison
• Open-collector output structure supporting flexible logic interfacing
• Low power consumption suitable for battery-operated systems

Comparators Applications

• Threshold detection circuits
• Voltage monitoring systems
• Over-voltage protection designs

Comparators Procurement Notes

Verify the suffix 'VT' corresponds to the specific tape-and-reel packaging variant required for automated assembly processes. Confirm that the SOT-23-5 footprint matches the target PCB layout dimensions. Ensure the selected component meets the necessary RoHS compliance standards for the intended market. Cross-reference the manufacturer's latest datasheet revision to validate all electrical parameters against current design requirements.

Comparators Selection Notes

Select this component when a low-power, single-channel comparator with differential inputs is required. The open-collector output allows for easy interfacing with various logic families. Consider the 180 ns response time for speed-sensitive applications. The wide supply voltage range accommodates both single and dual supply configurations. Evaluate the thermal performance within the specified operating temperature range.

Comparators Part Context

This part belongs to the TLV1391 series of analog comparators from Texas Instruments. The series is designed for general-purpose comparison tasks requiring low power and small form factors. The IDBVT designation indicates the industrial temperature grade and the specific SOT-23-5 reel packaging. It serves as a compact alternative to larger package comparators in space-constrained designs.

Comparators Replacement Considerations

Check for pin-compatible alternatives such as the TLV1391IDBVR if cut-tape packaging is preferred instead of reels. Verify functional equivalence regarding input offset voltage and response time when substituting with other single-channel comparators.
