Instructions for Use

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the range of 4.75V to 5.25V.
    • Connect the ground (GND) pin to a stable 0V reference.
  2. Input Signals:

    • Input signals should be within the specified voltage levels:
      • Low input (VIL): 0V to 0.8V
      • High input (VIH): 2.0V to VCC
  3. Output Signals:

    • The output will be:
      • Low (VOL): 0V to 0.4V
      • High (VOH): 2.4V to VCC - 0.5V
  4. Propagation Delay:

    • The propagation delay time (tpd) is typically 15ns but can vary between 15ns and 35ns.
  5. Power Dissipation:

    • The maximum power dissipation (PTOT) is 100mW. Ensure adequate heat dissipation if operating near this limit.
  6. Temperature Ranges:

    • Operating Temperature (TA): -40°C to 85°C
    • Storage Temperature (TSTG): -65°C to 150°C
  7. Handling and Storage:

    • Store the device in a dry, cool place to avoid moisture damage.
    • Handle with care to prevent static discharge, which can damage the device.
  8. Mounting:

    • Ensure proper mounting to a PCB with appropriate soldering techniques.
    • Verify all connections are secure and free from shorts or open circuits.
  9. Testing:

    • Test the device under controlled conditions to ensure it meets the specified parameters.
    • Use a multimeter or oscilloscope to verify input and output voltages and timing characteristics.
