LMC7221AIM5

Texas Instruments · Comparators · SOT-23-5

LMC7221AIM5 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 Open-drain comparator output that only pulls low and needs an external pull-up resistor, which can go to a voltage up to 15V above or below the supply; rated for 15V at the pin and ±30mA.
2 V+ power_in Positive supply pin, operating range 2.7V to 15V (16V absolute maximum between V+ and V−).
3 NON-INVERTING INPUT input Non-inverting (+) comparator input with a common-mode range that extends beyond both V− and V+, limited to V+ +0.3V and V− −0.3V.
4 INVERTING INPUT input Inverting (−) comparator input with a common-mode range that extends beyond both V− and V+, limited to V+ +0.3V and V− −0.3V.
5 V- power_in Negative supply pin, normally connected to ground (0V) in single-supply operation.
