According to typical Highway09A Circuit Overviews , the 16-pin layout manages critical timing and sensing tasks:
If the IC is on a board, look for silkscreen labels (e.g., U1 , IC5 ) and trace connections to determine its function (power, signal, logic).
The HIGHWAY09A is versatile and used across various sectors:
| Pin No. | Name | Typical Function | |---------|------------|---------------------------------------------| | 1 | VCC | Power supply input (e.g., 5V or 12V) | | 2 | GND | Ground reference | | 3 | TXD | Transmit data input (for bus drivers) | | 4 | RXD | Receive data output | | 5 | EN | Enable pin (active high or low) | | 6 | STB | Standby mode control | | 7 | CANH/LINH | Bus high line (for differential signaling) | | 8 | CANL/LINL | Bus low line | | 9-16 | NC / Other | No connect or secondary functions (e.g., thermal pad) |
