Instructions for Use:

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the specified range of 1.65 V to 3.6 V.
    • Use a stable power source to avoid voltage fluctuations that can affect performance.
  2. Input Signals:

    • Input voltages should be within the valid logic levels:
      • VIH (High) should be between 2.0 V and VCC.
      • VIL (Low) should be between 0 V and 0.8 V.
    • Avoid input voltages outside these ranges to prevent damage or undefined behavior.
  3. Output Signals:

    • The output high (VOH) should be at least 2.4 V when VCC is 3.3 V and the output low (VOL) should not exceed 0.4 V under the same conditions.
    • Ensure the load connected to the outputs does not exceed the maximum current ratings.
  4. Propagation Delay:

    • The propagation delay times (tPLH and tPHL) are typically 2.5 ns at VCC = 3.3 V and ambient temperature (TA) = 25°C.
    • These values may vary with different operating conditions, so ensure your design accounts for potential variations.
  5. Temperature Considerations:

    • The device operates reliably over a temperature range from -40°C to 85°C.
    • For storage, the temperature range is -65°C to 150°C.
    • Avoid exposing the device to temperatures outside these ranges to prevent damage.
  6. Power Dissipation:

    • The maximum power dissipation is 350 mW at an ambient temperature of 70°C.
    • Ensure adequate heat dissipation if the device is expected to operate near its maximum power dissipation limit.
  7. Handling and Storage:

    • Handle the device with care to avoid static discharge, which can damage sensitive components.
    • Store the device in a dry, cool environment to prevent moisture damage.

By following these guidelines, you can ensure reliable operation and longevity of the 74LVCH32245AEC device.
