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

RS1T34XF5 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 VCCA power_in A port supply voltage; operates from 1.65 V to 5.5 V and is the supply associated with the A input port.
2 A input Input A, referenced to VCCA; the A bus is the input side of the 1-bit unidirectional transceiver.
3 GND power_in Ground reference for the device.
4 B output Output B, referenced to VCCB; the B bus is the output side and is high-impedance when either VCC is at GND.
5 VCCB power_in B port supply voltage; operates from 1.65 V to 5.5 V and is the supply associated with the B output port.
