Power Supply:
- Ensure the supply voltage (V_CC) is within the specified range (4.75V to 5.25V) to avoid damage to the device.
Input Levels:
- For a logic high input, the voltage should be between 2.0V and V_CC.
- For a logic low input, the voltage should be between 0V and 0.8V.
Output Levels:
- The output high voltage (V_OH) should be at least 2.4V when sourcing up to 0.4 mA.
- The output low voltage (V_OL) should be no more than 0.5V when sinking up to 16 mA.
Propagation Delay:
- The propagation delay time (t_pd) is typically 35 ns but can vary between 35 ns and 60 ns under standard operating conditions.
Power Dissipation:
- The maximum power dissipation per package is 500 mW. Ensure proper heat dissipation if operating near this limit.
Temperature Range:
- The device is rated for operation from 0掳C to 70掳C for commercial grade applications.
- Store the device in a temperature range from -65掳C to 150掳C.
Handling:
- Handle with care to avoid static discharge which can damage the device.
- Follow standard ESD (Electrostatic Discharge) precautions during handling and installation.
Mounting:
- Ensure proper mounting on a PCB to maintain thermal and electrical performance.
- Use appropriate soldering techniques and avoid excessive heat during soldering.
Testing:
- Before integrating into a larger system, test the device under typical operating conditions to ensure it meets the required specifications.
