Power Supply Connection:
- Connect the VCC pin to a power supply between 2.0V and 6.0V.
- Ensure GND is properly grounded.
Direction Control:
- Use the DIR pin to control the direction of data transfer. A high signal on DIR allows data to flow from A to B; a low signal enables data transfer from B to A.
Enable/Disable Functionality:
- The OE (Output Enable) pin controls whether the outputs are active or in high-impedance state. Set OE low to enable the buffer, set it high to disable.
Signal Integrity:
- Keep signal paths as short as possible to minimize noise and ensure reliable operation.
- Use proper decoupling capacitors near the power pins to stabilize the supply voltage.
Temperature Considerations:
- Ensure the device operates within the temperature range of -40掳C to 85掳C for optimal performance.
Handling Static Electricity:
- Handle the IC with care to avoid damage from static electricity. Use anti-static measures when handling.
Propagation Delay:
- Be aware of the propagation delay time (tpd) which can affect timing-sensitive applications. Adjust your design accordingly to accommodate this delay.
Power Dissipation:
- Monitor the power dissipation to ensure it does not exceed 470mW to prevent overheating and potential damage to the device.
