Instructions for Use:

1. Power Supply: Ensure the supply voltage (VCC) is within the range of 2.0V to 5.5V. The device can operate over this voltage range without damage.

2. Input Levels: For reliable operation, input signals should be below 0.8V for a low logic level and above 2.0V for a high logic level.

3. Output Levels: When sourcing or sinking current up to 4mA, the output voltages will remain within specified limits (VOL ≤ 0.4V for low, VOH ≥ 2.4V for high).

4. Propagation Delay: At nominal conditions (VCC = 5V, ambient temperature = 25°C), expect propagation delays between 9ns and 13ns.

5. Thermal Considerations: Keep power dissipation under 670mW to avoid overheating. Ensure adequate heat sinking if operating near maximum power.

6. Temperature Range: Operate within -40°C to 85°C for optimal performance. Storage temperatures can range from -65°C to 150°C.

7. Handling: This device is sensitive to electrostatic discharge (ESD). Use proper ESD protection during handling and installation.

8. Applications: Suitable for bus interface applications requiring bidirectional data transfer with TTL/CMOS compatibility.
