Instructions for Use:

1. Power Supply Connection: Connect the VCC pin to a power supply between 4.5V and 5.5V, and connect GND to ground.
2. Direction Control: Use the direction control pin (DIR) to set the data transfer direction. When DIR is high, data flows from A to B; when low, data flows from B to A.
3. Output Enable: The output enable pin (OE) must be active (low) for data to pass through. If OE is high, all outputs are in a high-impedance state.
4. Data Lines: Connect the A and B data lines according to your application needs. Ensure that signal integrity is maintained by using proper PCB layout practices.
5. Decoupling Capacitors: Place decoupling capacitors close to the VCC and GND pins to minimize noise and transient voltage spikes.
6. Handling Precautions: Handle the device with care to avoid ESD damage. Use appropriate ESD protection measures during assembly and testing.
