TXB0104D from Texas Instruments, in a SOIC-14. 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 power supply voltage input; 1.2V ≤ VCCA ≤ 3.6V and VCCA ≤ VCCB required. |
| 2 | A1 | bidirectional | Input/Output 1 referenced to VCCA; bidirectional I/O with automatic direction sensing. |
| 3 | A2 | bidirectional | Input/Output 2 referenced to VCCA; bidirectional I/O with automatic direction sensing. |
| 4 | A3 | bidirectional | Input/Output 3 referenced to VCCA; bidirectional I/O with automatic direction sensing. |
| 5 | A4 | bidirectional | Input/Output 4 referenced to VCCA; bidirectional I/O with automatic direction sensing. |
| 6 | NC | unconnected | No connection; no internal connection. |
| 7 | GND | power_in | Ground. |
| 8 | OE | input | Three-state output mode enable referenced to VCCA; pull low to place all outputs in three-state mode. |
| 9 | NC | unconnected | No connection; no internal connection. |
| 10 | B4 | bidirectional | Input/Output 4 referenced to VCCB; bidirectional I/O with automatic direction sensing. |
| 11 | B3 | bidirectional | Input/Output 3 referenced to VCCB; bidirectional I/O with automatic direction sensing. |
| 12 | B2 | bidirectional | Input/Output 2 referenced to VCCB; bidirectional I/O with automatic direction sensing. |
