Pinout
The pin configuration is as follows:
1. Control Pins:
- OE (Output Enable, active low): Enables or disables the transceiver function.
- DIR (Direction Control): Determines the direction of data flow.
2. Data Pins:
- A1 to A8: Data bus A inputs/outputs.
- B1 to B8: Data bus B inputs/outputs.
3. Power Pins:
- VCC: Power supply pin.
- GND: Ground pin.
When OE is low, data can be transmitted from A to B if DIR is high, or from B to A if DIR is low. When OE is high, both A and B outputs are in high-impedance state, effectively isolating the buses.
