RS1T45XC6 from Jiangsu RUNIC Tech, in a SOT-363. 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, which must be between 1.65V and 5.5V (1.65V ≤ VCCA ≤ 5.5V).
2 GND power_in Ground reference for the device.
3 A bidirectional Input/output A, referenced to VCCA; it is the A-bus data port and is enabled when DIR is low.
4 B bidirectional Input/output B, referenced to VCCB; it is the B-bus data port and is enabled when DIR is high.
5 DIR input Direction control input referenced to VCCA; high selects A-to-B transfer and low selects B-to-A transfer.
6 VCCB power_in B port supply voltage, which must be between 1.65V and 5.5V (1.65V ≤ VCCB ≤ 5.5V).
