Product Overview

The LMV7239 is a Texas Instruments low-power rail-to-rail comparator in the Signal_Chain category. The LMV7239 variant uses a push-pull output and is specified for a recommended supply range of 2.7 to 5.5 V with operation from -40 to 85 °C.

Dynamic performance is defined across 2.7 V and 5 V supplies. Typical propagation delay is 75 ns at 5 V with 100 mV overdrive and 85 ns at 2.7 V with 100 mV overdrive, both with 15 pF load. Output transition timing is 1.2 ns typical rise and fall time at 5 V, and 1.7 ns typical at 2.7 V.

The device is offered in 5-pin SOT-23 (DBV) and 5-pin SC70 (DGK) packages. Pin functions are VOUT, V-, IN+, IN-, and V+. These facts support compact comparator layouts for signal-chain circuits that need low supply current, rail-to-rail common-mode input range, and defined push-pull output behavior.
