Instructions for Use:

1. Power Supply: Ensure the supply voltage (VCC) is within the operating range of 3.0V to 5.5V.
2. Signal Levels:
   • For driver output low (VOL), ensure the load current (IOL) does not exceed 250mA to maintain a maximum output voltage of 0.4V.
   • For driver output high (VOH), ensure the load current (IOH) is such that the output voltage remains at or below 5.0V.
3. Receiver Operation:
   • The receiver input threshold (VIH, VIL) should be set according to the specific application requirements.
   • Keep input leakage current (IIH, IIL) within the specified limit to avoid erroneous readings.
4. Timing Considerations:
   • Account for propagation delay (tPD) in your system design, which can vary between 28ns and 40ns.
5. Environmental Conditions:
   • Operate the device within the temperature range of -40°C to 85°C to ensure reliable performance.
6. Handling Precautions:
   • Handle the device with care to prevent damage from electrostatic discharge (ESD).
   • Follow standard precautions for surface-mount components during soldering and assembly.

Package Information:

• Package Type: 8-SOIC
