# RS1G126XC5

**Jiangsu RUNIC Tech** · Buffers, Drivers, Receivers, Transceivers · SC70-5

RS1G126XC5 from Jiangsu RUNIC Tech, in a SC70-5. 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 | Output-enable input; when OE is low the output is disabled to the high-impedance (Z) state, and OE should be tied to GND through a pulldown resistor to ensure high impedance during power-up and power-down. |
| 2 | A | input | Data input to the single buffer gate, with Y following A while the output is enabled. |
| 3 | GND | power_in | Ground pin. |
| 4 | Y | tri_state | 3-state buffer output, driven from A when OE is high and high-impedance when OE is low. |
| 5 | VCC | power_in | Power supply pin; the device is specified for operation from 1.65 V to 5.5 V. |
