LMV7239M5X

Overview

The LMV7239M5X is a single-channel analog comparator from Texas Instruments, housed in a 5-pin SOT-23 package. It operates within a supply voltage range of 2.7 V to 5.5 V and features rail-to-rail input capability. The device provides a push-pull output stage with a propagation delay of 75 ns at 5 V. Key electrical parameters include a maximum input offset voltage of 8 mV, an input bias current of 400 nA, and a quiescent supply current of 95 µA. It supports a short-circuit output current of 60 mA and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Rail-to-rail input common-mode voltage range extending beyond ground and supply rails
• Push-pull output stage eliminating the need for external pull-up resistors
• Ultra-low power consumption suitable for battery-operated systems

Applications

• Battery-powered portable electronics
• Threshold detection circuits
• Voltage monitoring systems

Procurement Notes

Verify the specific suffix 'M5X' corresponds to the SOT-23-5 tape-and-reel packaging configuration. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance if required by the assembly process. Ensure the operating environment remains within the specified -40°C to +85°C temperature range to maintain guaranteed performance specifications.

Selection Notes

Select this component when a low-power, single-supply comparator with rail-to-rail inputs is required. The push-pull output distinguishes it from open-drain variants like the LMV7235, simplifying circuit design by removing the need for external pull-up components. It is appropriate for applications where moderate speed (75 ns) is acceptable in exchange for minimal current draw.

Part Context

This part belongs to the LMV723x family of ultra-low power comparators. It shares the same internal architecture as the LMV7235 but differs in output topology. While the LMV7235 utilizes an open-drain output requiring external termination, the LMV7239 integrates a push-pull stage. Both devices offer identical input characteristics and power efficiency profiles.

Replacement Considerations
