Instructions for Use:
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.
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).
Input Current:
- The input current should be kept low to minimize power consumption.
- Ensure that the input current does not exceed 10μA to maintain optimal performance.
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°C, the typical propagation delay is 7ns.
Power Dissipation:
- The maximum power dissipation per package is 150mW.
- Ensure proper heat dissipation if operating near this limit to prevent overheating.
Operating and Storage Temperature:
- The device can operate within a temperature range of -40°C to 85°C.
- Store the device in an environment with temperatures between -65°C and 150°C.
Handling:
- Handle the device with care to avoid static damage.
- Follow ESD (Electrostatic Discharge) precautions when handling the component.
Mounting:
- Ensure proper soldering and mounting techniques to avoid mechanical stress on the device.
- Use appropriate PCB layout guidelines to ensure reliable operation.
