TLV1391IDBVR

Comparators Overview

The TLV1391IDBVR is a single-channel analog comparator manufactured by Texas Instruments, housed in an SOT-23-5 surface-mount 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 per channel. Key electrical specifications include a response time of 180 ns, an input offset voltage of 5 mV, and an input bias current of 400 nA at 5 V. It supports differential input configurations and functions reliably across an operating temperature range from -40°C to +85°C.

Comparators Feature Summary

• Supports low-voltage operation with a minimum supply of 2 V
• Features high-speed differential comparison with 180 ns response time
• Provides flexible open-collector output for interfacing with various logic levels

Comparators Applications

• Battery-powered portable devices requiring low standby current
• Threshold detection circuits in industrial control systems
• Signal conditioning stages in sensor interfaces

Comparators Procurement Notes

Verify the complete part number including the suffix 'DBVR' to ensure the correct SOT-23-5 package and tape-and-reel packaging configuration. Confirm that the application environment remains within the specified -40°C to +85°C temperature limits. Ensure the load connected to the open-collector output does not exceed the 20 mA maximum sink current rating. Check for any specific RoHS compliance documentation requirements relevant to your region.

Comparators Selection Notes

Select this component when a low-power, single-channel comparator is needed for applications with limited supply voltage headroom. The open-collector output allows for easy level shifting without additional components. Consider the 180 ns propagation delay if signal integrity at higher frequencies is critical. Compare against other TLV series comparators if shutdown functionality or rail-to-rail outputs are required instead.

Comparators Part Context

This device belongs to the TLV1391 family of low-power analog comparators designed for general-purpose applications. It shares the same functional core as variants with different packaging or temperature grades but is specifically configured for surface-mount assembly in compact designs. The family emphasizes power efficiency while maintaining adequate speed for standard digital interface tasks.

Comparators Replacement Considerations

Direct substitutes include other single-channel comparators in SOT-23-5 packages with similar voltage ranges and open-collector outputs. Verify pinout compatibility before swapping. Alternative parts may offer different propagation delays or quiescent currents; ensure these parameters meet the specific circuit requirements.
