SN74LVT245BDWR from Texas Instruments, in a SOIC-20-300mil. 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 | DIR | input | Direction control input; low selects B bus data to A bus transmission, high selects A bus data to B bus transmission. |
| 2 | A1 | bidirectional | Bus A transceiver data line bit 1 with mixed-mode 5-V input/output support on 3.3-V core. |
| 3 | A2 | bidirectional | Bus A transceiver data line bit 2 with mixed-mode 5-V input/output support on 3.3-V core. |
| 4 | A3 | bidirectional | Bus A transceiver data line bit 3 with mixed-mode 5-V input/output support on 3.3-V core. |
| 5 | A4 | bidirectional | Bus A transceiver data line bit 4 with mixed-mode 5-V input/output support on 3.3-V core. |
| 6 | A5 | bidirectional | Bus A transceiver data line bit 5 with mixed-mode 5-V input/output support on 3.3-V core. |
| 7 | A6 | bidirectional | Bus A transceiver data line bit 6 with mixed-mode 5-V input/output support on 3.3-V core. |
| 8 | A7 | bidirectional | Bus A transceiver data line bit 7 with mixed-mode 5-V input/output support on 3.3-V core. |
| 9 | A8 | bidirectional | Bus A transceiver data line bit 8 with mixed-mode 5-V input/output support on 3.3-V core. |
| 10 | GND | power_in | Ground reference (0 V). |
| 11 | B8 | bidirectional | Bus B transceiver data line bit 8 with mixed-mode 5-V input/output support on 3.3-V core. |
| 12 | B7 | bidirectional | Bus B transceiver data line bit 7 with mixed-mode 5-V input/output support on 3.3-V core. |
| 13 | B6 | bidirectional | Bus B transceiver data line bit 6 with mixed-mode 5-V input/output support on 3.3-V core. |
| 14 | B5 | bidirectional | Bus B transceiver data line bit 5 with mixed-mode 5-V input/output support on 3.3-V core. |
| 15 | B4 | bidirectional | Bus B transceiver data line bit 4 with mixed-mode 5-V input/output support on 3.3-V core. |
| 16 | B3 | bidirectional | Bus B transceiver data line bit 3 with mixed-mode 5-V input/output support on 3.3-V core. |
| 17 | B2 | bidirectional | Bus B transceiver data line bit 2 with mixed-mode 5-V input/output support on 3.3-V core. |
| 18 | B1 | bidirectional | Bus B transceiver data line bit 1 with mixed-mode 5-V input/output support on 3.3-V core. |
| 19 | OE | input | Output enable control input; low enables transceiver outputs, high places all outputs in high-impedance state. |
| 20 | VCC | power_in | Power supply voltage (2.7 V to 3.6 V nominal), supports mixed-mode 5-V signal operation. |
