# LMV7239QM7X

**Texas Instruments** · Comparators · SC-70-5

LMV7239QM7X from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUT | output | Push-pull comparator output that drives the rail-to-rail logic swing without requiring an external pull-up resistor. |
| 2 | V- | power_in | Negative supply pin, held at 0 V (GND) in the datasheet test conditions for single-supply operation. |
| 3 | IN+ | input | Noninverting comparator input with a common-mode range of −0.2 V to 5.2 V at 5 V supply (−0.2 V to 2.9 V at 2.7 V supply, CMRR > 50 dB). |
| 4 | IN- | input | Inverting comparator input with the same common-mode range of −0.2 V to 5.2 V at 5 V supply (−0.2 V to 2.9 V at 2.7 V supply, CMRR > 50 dB). |
| 5 | V+ | power_in | Positive supply pin; the device is specified for 2.7 V to 5.5 V across V+ to V-, with a 0.1-µF ceramic decoupling capacitor recommended as close to this pin as possible. |
