Instructions for Use:
Power Supply:
- Ensure the supply voltage (VDD) is within the specified range (3V to 15V).
- Connect VSS to ground (0V).
Input Signals:
- Apply input signals such that the low level (VIL) is below 1.5V and the high level (VIH) is above 3.5V when VDD is 5V.
- Avoid exceeding the maximum ratings for input voltages.
Output Signals:
- The output low voltage (VOL) should be less than 0.6V when sourcing up to 4mA.
- The output high voltage (VOH) should be greater than 2.4V when sinking up to -0.4mA.
Timing Considerations:
- Account for the propagation delay time (tpd) which can range from 35ns to 100ns depending on the operating conditions.
Thermal Management:
- Ensure the device operates within the specified temperature range (-40°C to 85°C).
- Store the device within the storage temperature range (-65°C to 150°C).
Handling:
- Handle the device with care to avoid static damage.
- Follow proper soldering techniques to prevent thermal shock.
Testing:
- Test the device under typical operating conditions to ensure it meets the specified performance parameters.
Applications:
- Suitable for use in digital logic circuits, multiplexers, and data selectors.
