Instructions for Use:

1. Supply Voltage:

   • Ensure the supply voltage (VCC) is within the range of 2.0V to 5.5V.
   • Do not exceed the maximum supply voltage to avoid damaging the device.

2. Output Current:

   • The device can source up to 16mA and sink up to 32mA per output.
   • For reliable operation, keep the current within the typical values (8mA for sourcing, 16mA for sinking).

3. Input Current:

   • The input current should be kept low to minimize power consumption.
   • Ensure that the input current does not exceed 10渭A to maintain optimal performance.

4. Propagation Delay:

   • The propagation delay time (tpd) is crucial for timing considerations in your circuit.
   • At a supply voltage of 5V and ambient temperature of 25掳C, the typical propagation delay is 7ns.

5. Power Dissipation:

   • The maximum power dissipation per package is 150mW.
   • Ensure proper heat dissipation if operating near this limit to prevent overheating.

6. Operating and Storage Temperature:

   • The device can operate within a temperature range of -40掳C to 85掳C.
   • Store the device in an environment with temperatures between -65掳C and 150掳C.

7. Handling:

   • Handle the device with care to avoid static damage.
   • Follow ESD (Electrostatic Discharge) precautions when handling the component.

8. Mounting:

   • Ensure proper soldering and mounting techniques to avoid mechanical stress on the device.
   • Use appropriate PCB layout guidelines to ensure reliable operation.
