Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DIR | input | Direction control input; LOW enables A to B transfer, HIGH enables B to A transfer when OE is LOW. |
| 2 | A0 | bidirectional | Data input/output bit 0; bidirectional bus interface for A bus with 3-state control. |
| 3 | A1 | bidirectional | Data input/output bit 1; bidirectional bus interface for A bus with 3-state control. |
| 4 | A2 | bidirectional | Data input/output bit 2; bidirectional bus interface for A bus with 3-state control. |
| 5 | A3 | bidirectional | Data input/output bit 3; bidirectional bus interface for A bus with 3-state control. |
| 6 | A4 | bidirectional | Data input/output bit 4; bidirectional bus interface for A bus with 3-state control. |
| 7 | A5 | bidirectional | Data input/output bit 5; bidirectional bus interface for A bus with 3-state control. |
| 8 | A6 | bidirectional | Data input/output bit 6; bidirectional bus interface for A bus with 3-state control. |
| 9 | A7 | bidirectional | Data input/output bit 7; bidirectional bus interface for A bus with 3-state control. |
| 10 | GND | power_in | Ground (0 V); power return. |
| 11 | B7 | bidirectional | Data input/output bit 7; bidirectional bus interface for B bus with 3-state control. |
| 12 | B6 | bidirectional | Data input/output bit 6; bidirectional bus interface for B bus with 3-state control. |
| 13 | B5 | bidirectional | Data input/output bit 5; bidirectional bus interface for B bus with 3-state control. |
| 14 | B4 | bidirectional | Data input/output bit 4; bidirectional bus interface for B bus with 3-state control. |
| 15 | B3 | bidirectional | Data input/output bit 3; bidirectional bus interface for B bus with 3-state control. |
| 16 | B2 | bidirectional | Data input/output bit 2; bidirectional bus interface for B bus with 3-state control. |
| 17 | B1 | bidirectional | Data input/output bit 1; bidirectional bus interface for B bus with 3-state control. |
| 18 | B0 | bidirectional | Data input/output bit 0; bidirectional bus interface for B bus with 3-state control. |
| 19 | OE | input | Output enable input (active LOW); HIGH places all outputs in high-impedance state. |
| 20 | VCC | power_in | Supply voltage; 4.5 V to 5.5 V for 74HCT245. |
