HT3201ARTZ from HTCSEMI, 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 | OUT | output | Push-pull comparator output with 40 ns propagation delay, sinking up to 48 mA and sourcing up to 60 mA short-circuit current typical at VCC = 5 V. |
| 2 | GND | power_in | Negative supply, ground; use an unbroken low-inductance ground plane. |
| 3 | IN+ | input | Positive input of the rail-to-rail comparator with common-mode range from (VEE) - 0.2 V to (VCC) + 0.2 V. |
| 4 | IN- | input | Negative input of the rail-to-rail comparator with common-mode range from (VEE) - 0.2 V to (VCC) + 0.2 V. |
| 5 | VCC | power_in | Positive supply, specified from 2.7 V to 5.5 V (absolute maximum 7 V), with a 0.1 uF ceramic decoupling capacitor placed close to it. |
