# LMH7220MK

**Texas Instruments** · Comparators · SOT-23-Thin-6

LMH7220MK from Texas Instruments, in a SOT-23-Thin-6. 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 | IN- | input | Inverting input of the differential pair; input voltage range extends 200 mV below ground allowing ground-sensing applications |
| 2 | GND | power_in | Ground reference |
| 3 | OUT Q | output | Non-inverting LVDS output; delivers 325 mV differential swing into 100Ω load with 2.9 ns propagation delay at 100 mV overdrive and 0.6 ns rise/fall times |
| 4 | OUT Q | output | Inverting LVDS output complementary to OUT Q; 325 mV differential swing into 100Ω load with equal 0.6 ns rise/fall times |
| 5 | VCC | power_in | Positive supply voltage; 2.7V to 12V operating range with 6.8 mA supply current at 5V |
| 6 | IN+ | input | Non-inverting input of the differential pair; input voltage range extends 200 mV below ground allowing ground-sensing applications |
