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). |
