# LMC7211AIM5

**Texas Instruments** · Comparators · SOT-23-5

LMC7211AIM5 from Texas Instruments, in a SOT-23-5. 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 | OUTPUT | output | Push-pull comparator output that sources 30mA and sinks 45mA short-circuit current; output current is rated ±30mA absolute maximum. |
| 2 | V+ | power_in | Positive supply pin, specified for 2.7V to 15V operation (16V absolute maximum between V+ and V-). |
| 3 | NON-INVERTING INPUT | input | Non-inverting (+) comparator input with rail-to-rail common-mode range extending 0.3V beyond V- and V+ typical, input current limited to ±5mA. |
| 4 | INVERTING INPUT | input | Inverting (-) comparator input with rail-to-rail common-mode range extending 0.3V beyond V- and V+ typical, input current limited to ±5mA. |
| 5 | V- | power_in | Negative supply pin (ground in single-supply use), reference for the 2.7V to 15V supply range. |
