The device is provided in an 8-pin VSSOP (DGK) package. Here is a brief overview of its pin functions:
1. Pin 1 (R): Receiver output; delivers the recovered data from the differential bus to the local node.
2. Pin 2 (RE): Receiver enable; active-low input that enables the receiver when low.
3. Pin 3 (DE): Driver enable; controls the driver outputs, enabling them when high.
4. Pin 4 (D): Driver input; accepts data that is to be sent out on the differential bus.
5. Pin 5 (GND): Ground connection for the device.
6. Pin 6 (A): Non-inverting driver output and non-inverting receiver input.
7. Pin 7 (B): Inverting driver output and inverting receiver input.
8. Pin 8 (VCC): Power supply input.
This arrangement helps facilitate reliable data transmission in half-duplex communication systems.
