RS8904XF from Jiangsu RUNIC Tech, in a SOT23-5. 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 CMOS comparator output that swings rail to rail and can source up to 46 mA and sink up to 40 mA at a 5 V supply, as stated in the output current section. |
| 2 | GND | power_in | Ground reference pin; the layout guidelines call for an unbroken low-inductance ground plane with the ground trace running under the device up to the bypass capacitor. |
| 3 | IN+ | input | Positive comparator input with a rail-to-rail common-mode range from (V-) - 0.1 V to (V+) + 0.1 V over temperature, and signal input pins are diode-clamped with inputs swinging more than 0.3 V beyond the rails to be current-limited to 10 mA or less. |
| 4 | IN- | input | Negative comparator input with the same common-mode range of (V-) - 0.1 V to (V+) + 0.1 V, and signal input pins are diode-clamped with inputs swinging more than 0.3 V beyond the rails to be current-limited to 10 mA or less. |
| 5 | VCC | power_in | Positive (highest) power supply pin with a specified single-supply operating range of 2.7 V to 5.5 V and an absolute maximum supply voltage of 7 V. |
