RS1G126XF5

Jiangsu RUNIC Tech · Buffers, Drivers, Receivers, Transceivers · SOT23-5

RS1G126XF5 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 Output-enable input: when OE is low the output goes to high-impedance (Z), and OE should be tied to GND through a pulldown resistor to keep the output high-impedance during power-up and power-down, with the minimum resistor value set by the driver's current-sourcing capability.
2 A input Data input of the single bus buffer; inputs accept voltage up to 5.5V regardless of VCC.
3 GND power_in Ground pin.
4 Y output 3-state buffer output with ±24mA output drive at VCC=3.0V, which is high-impedance when OE is low; continuous output current is rated ±50mA.
5 VCC power_in Supply pin; the operating supply range is 1.65V to 5.5V.
