Instructions for TCA780D

1. Power Supply Connection:

   • Connect the VDD pin to a stable power supply within the range of 4.5V to 5.5V.
   • Ensure that the GND pin is connected to the common ground.

2. Input Signals:

   • Apply logic level input signals (0V to VDD) to the input pins.
   • Ensure that the input voltage does not exceed VDD to prevent damage.

3. Output Handling:

   • The device can source up to 100mA per channel. Do not exceed this limit to avoid overheating.
   • Use appropriate heat sinking if operating at higher currents or temperatures.

4. Operating Temperature:

   • Ensure that the ambient temperature remains within -40掳C to 85掳C for reliable operation.
   • Monitor the junction temperature to ensure it does not exceed 125掳C.

5. Quiescent Current:

   • When no load is connected, the quiescent current should be around 1mA at 5V supply.

6. Propagation Delay:

   • Expect a propagation delay of approximately 10ns under typical conditions.

7. Storage and Handling:

   • Store in a dry environment away from direct sunlight.
   • Handle with care to avoid electrostatic discharge which can damage the component.
