Instructions

1. Power Supply:

   • Connect the Vcc pin to a stable 5V power supply.
   • Ensure the ground (GND) pin is properly connected to the system ground.

2. Input Connections:

   • Connect the input signals to the appropriate input pins (IN1, IN2, etc.).
   • Ensure that the input voltages are within the specified range (0 V to Vcc).

3. Output Connections:

   • Connect the output pins (OUT1, OUT2, etc.) to the load or next stage of the circuit.
   • Do not exceed the maximum output current rating of ±30 mA per channel.

4. Decoupling Capacitors:

   • Place a 0.1 μF ceramic capacitor close to the Vcc and GND pins to filter out noise and provide stable operation.

5. Temperature Considerations:

   • Operate the IC within the specified temperature range (-40°C to +85°C) to ensure reliable performance.
   • Avoid exposing the IC to extreme temperatures or rapid temperature changes.

6. Handling Precautions:

   • Handle the IC with care to avoid damage from electrostatic discharge (ESD).
   • Use proper ESD protection measures such as wrist straps and grounded work surfaces.

7. Layout Recommendations:

   • Keep signal traces short and direct to minimize noise and interference.
   • Use ground planes to improve signal integrity and reduce electromagnetic interference (EMI).

8. Testing:

   • Before finalizing the design, test the IC under various operating conditions to ensure it meets the required specifications.
   • Use an oscilloscope to verify the propagation delay and rise/fall times of the output signals.
