RS1G125XF5 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 | OE | input | Active-low output enable input; when OE is high the output Y is disabled to high impedance, and OE should be tied to VCC through a pullup resistor (minimum value set by the driver's current-sinking capability) to hold the high-impedance state during power up or power down. |
| 2 | A | input | Data input of the buffer; input voltage range is 0 V to 5.5 V regardless of VCC, per the recommended operating conditions. |
| 3 | GND | power_in | Ground pin for the device. |
| 4 | Y | tri_state | Three-state buffer output, high impedance when OE is high, with ±24 mA drive at VCC=3.0 V and continuous output current limited to ±50 mA. |
| 5 | VCC | power_in | Supply pin; operating range is 1.65 V to 5.5 V, with data retention down to 1.5 V. |
