TXS0104EDR from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCCA | power_in | A-port supply voltage. 1.65 V ≤ VCCA ≤ 3.6 V, with VCCA ≤ VCCB. Also supplies the OE input circuitry. |
| 2 | A1 | bidirectional | Input/output A1, referenced to VCCA. Push-pull or open-drain translation channel; pair with pin 13 (B1). |
| 3 | A2 | bidirectional | Input/output A2, referenced to VCCA. Pair with pin 12 (B2). |
| 4 | A3 | bidirectional | Input/output A3, referenced to VCCA. Pair with pin 11 (B3). |
| 5 | A4 | bidirectional | Input/output A4, referenced to VCCA. Pair with pin 10 (B4). |
| 6 | NC | unconnected | No internal connection. May be left floating or tied to GND for layout convenience. |
| 7 | GND | power_in | Device ground reference for both A and B port supplies. |
| 8 | OE | input | 3-state output-mode enable, referenced to VCCA. Pull low to place all A and B outputs in Hi-Z (VIL ≤ 0.35 × VCCA; VIH ≥ 0.65 × VCCA, max 5.5 V). Tie to GND through a pull-down for defined Hi-Z during power-up/down. |
| 9 | NC | unconnected | No internal connection. May be left floating or tied to GND for layout convenience. |
| 10 | B4 | bidirectional | Input/output B4, referenced to VCCB. Pair with pin 5 (A4). |
| 11 | B3 | bidirectional | Input/output B3, referenced to VCCB. Pair with pin 4 (A3). |
| 12 | B2 | bidirectional | Input/output B2, referenced to VCCB. Pair with pin 3 (A2). |
| 13 | B1 | bidirectional | Input/output B1, referenced to VCCB. Pair with pin 2 (A1). |
| 14 | VCCB | power_in | B-port supply voltage. 2.3 V ≤ VCCB ≤ 5.5 V; must be greater than or equal to VCCA. |
