RS2G126XQ

Jiangsu RUNIC Tech · Buffer/Driver/Transceiver · TSSOP-8

RS2G126XQ from Jiangsu RUNIC Tech, in a TSSOP-8. 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 1OE input Output enable for buffer 1; output 1Y is high-impedance when 1OE is low, and OE should be tied to GND through a pulldown resistor to ensure high-impedance during power up or power down.
2 1A input Input of buffer 1; accepts voltages up to 5.5V and unused inputs must be held at VCC or GND.
3 2Y output 3-state output of buffer 2 with ±24mA drive at VCC=3.0V.
4 GND power_in Ground pin.
5 2A input Input of buffer 2; accepts voltages up to 5.5V and unused inputs must be held at VCC or GND.
6 1Y output 3-state output of buffer 1 with ±24mA drive at VCC=3.0V.
7 2OE input Output enable for buffer 2; output 2Y is high-impedance when 2OE is low, and OE should be tied to GND through a pulldown resistor to ensure high-impedance during power up or power down.
8 VCC power_in Power supply pin, operating range 1.65V to 5.5V.
