Texas Instruments LMV7239M7X-TI

Overview

LMV7239M7X-TI from Texas Instruments is a rail-to-rail input, push-pull output voltage comparator optimized for ultra-low-power, high-speed single-supply operation. It delivers 75 ns propagation delay at 5 V, draws only 65 µA supply current, supports 2.7 V to 5.5 V supply range, and features ±0.2 V beyond-rail input common-mode range - enabling ground- and supply-sensing in portable battery-powered systems.

For engineers reviewing the LMV7239M7X-TI datasheet, LMV7239M7X-TI pinout, LMV7239M7X-TI application, or LMV7239M7X-TI equivalent, key selection criteria include its push-pull output eliminating external pull-up resistors, guaranteed 75-ns timing at 5 V/15 pF, rail-to-rail input with extended common-mode range, low quiescent current across temperature, and compatibility with space-constrained SC70-5 layouts.

Technical Context

The LMV7239M7X-TI implements a complementary PNP/NPN input stage enabling true rail-to-rail input operation with common-mode range extending 200 mV below V− and 200 mV above V+, allowing direct sensing of ground-referenced or supply-referenced signals. Its push-pull output stage provides active sourcing and sinking without external components, delivering 4 mA high-level drive and 4 mA low-level sink capability at 5 V.

Propagation delay remains stable across temperature (±5 ns from −40°C to 85°C at 20 mV overdrive) and load capacitance (≤106 ns up to 100 pF), while input offset voltage is specified at ±1 mV (typ) and ±8 mV (max) over temperature - supporting precision threshold detection in low-voltage embedded control loops.

FAQ

What is the maximum operating temperature for LMV7239M7X-TI?

The LMV7239M7X-TI is rated for continuous operation from −40°C to +85°C ambient temperature, with junction temperature limited to 150°C. Thermal resistance θ_JA is 478°C/W for the SC70-5 package, so at 65 µA supply current and 5 V supply, self-heating remains negligible (<0.02°C) under typical PCB conditions - confirming full spec compliance across the industrial temperature range.

Does LMV7239M7X-TI require external pull-up resistors on its output?

No, LMV7239M7X-TI features a push-pull output stage and does not require external pull-up resistors. Unlike the open-drain LMV7235 variant, the LMV7239M7X-TI actively drives both logic high (to V+ − 0.25 V at 4 mA) and logic low (to 350 mV at −4 mA), enabling direct interface with CMOS/TTL inputs without additional components.

Can LMV7239M7X-TI operate from a 2.7 V single supply?

Yes, LMV7239M7X-TI is fully specified and guaranteed to operate from 2.7 V to 5.5 V single supply. At 2.7 V, propagation delay increases to 85 ns (100 mV overdrive, 15 pF), supply current drops to 52 µA, and output swing remains functional - making it ideal for single-cell Li-ion or alkaline-powered devices where headroom is constrained.

What is the input common-mode voltage range of LMV7239M7X-TI?

The LMV7239M7X-TI supports an input common-mode voltage range from V− − 0.2 V to V+ + 0.2 V. With V− = 0 V and V+ = 5 V, this means inputs may range from −0.2 V to +5.2 V - enabling direct connection to ground-referenced sensors or supply rails without attenuation or level-shifting circuitry.

Is LMV7239M7X-TI pin-compatible with LMV7235M7X-TI?

Yes, LMV7239M7X-TI and LMV7235M7X-TI share identical SC70-5 pinout (VOUT, V−, IN+, IN−, V+), same footprint, and identical recommended operating conditions. The sole functional difference is output architecture: LMV7239M7X-TI uses push-pull while LMV7235M7X-TI uses open-drain - requiring board-level redesign only for output termination, not pin mapping.
