TLV1391CDBVR

Comparators Overview

The TLV1391CDBVR is a single-channel analog comparator manufactured by Texas Instruments, housed in a surface-mount SOT-23-5 package. 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 up to 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 supports differential input configurations and functions reliably across an industrial temperature range from -40°C to +85°C.

Comparators Feature Summary

• Supports low-voltage operation with a wide supply range from 2 V to 7 V
• Features high-drive open-collector outputs for flexible interfacing
• Provides fast switching performance with a 180 ns response time

Comparators Applications

Comparators Procurement Notes

Verify the specific suffix 'C' against official Texas Instruments documentation to confirm the commercial grade temperature rating and exact electrical tolerances. Ensure the SOT-23-5 footprint matches the target PCB design. Confirm RoHS compliance status through the manufacturer's latest datasheet or orderable part number listing before finalizing procurement.

Comparators Selection Notes

Select this component when a single comparator with moderate speed and low power consumption is required. The open-collector output allows for easy level shifting to different logic voltages. Compare input offset voltage and bias current requirements against other TLV series comparators if higher precision or faster switching is needed for the specific application constraints.

Comparators Part Context

This device belongs to the TLV1391 family of low-power analog comparators designed for general-purpose applications. The family emphasizes energy efficiency while maintaining sufficient speed for most digital interface tasks. The SOT-23-5 packaging provides a compact solution suitable for space-constrained consumer and industrial electronic designs.

Comparators Replacement Considerations

Check for the TLV1391IDBVR variant, which offers improved input offset voltage specifications. Verify pinout compatibility and electrical parameter overlaps before substituting with other single-channel comparators in the SOT-23-5 package.
