CD74ACT245M96 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; selects A-to-B transmission (high) or B-to-A transmission (low). |
| 2 | A0 | bidirectional | A-bus bit 0, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 3 | A1 | bidirectional | A-bus bit 1, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 4 | A2 | bidirectional | A-bus bit 2, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 5 | A3 | bidirectional | A-bus bit 3, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 6 | A4 | bidirectional | A-bus bit 4, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 7 | A5 | bidirectional | A-bus bit 5, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 8 | A6 | bidirectional | A-bus bit 6, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 9 | A7 | bidirectional | A-bus bit 7, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 10 | GND | power_in | Ground reference pin. |
| 11 | B7 | bidirectional | B-bus bit 7, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 12 | B6 | bidirectional | B-bus bit 6, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 13 | B5 | bidirectional | B-bus bit 5, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 14 | B4 | bidirectional | B-bus bit 4, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 15 | B3 | bidirectional | B-bus bit 3, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 16 | B2 | bidirectional | B-bus bit 2, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 17 | B1 | bidirectional | B-bus bit 1, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
| 18 | B0 | bidirectional | B-bus bit 0, bidirectional transceiver I/O with three-state output control, voltage 0V to VCC. |
