Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the specified range (2.0V to 5.5V).
   • Connect the ground (GND) pin to the system ground.

2. Input Signals:

   • Apply input signals that meet the VIH and VIL specifications.
   • Ensure the input signals are within the valid voltage range to avoid damage or incorrect operation.

3. Output Signals:

   • The output signals will be within the VOH and VOL specifications.
   • Ensure the load connected to the output can handle the maximum output currents (IOH and IOL).

4. Propagation Delays:

   • Account for the propagation delays (tPLH and tPHL) in your timing calculations to ensure proper signal synchronization.

5. Power-on Reset:

   • Allow the device to reset properly by waiting for the power-on reset time (tPOR) before applying any input signals.

6. Temperature Considerations:

   • Operate the device within the specified operating temperature range (TOPR) to ensure reliable performance.
   • Store the device within the storage temperature range (TSTG) to prevent damage.

7. Handling Precautions:

   • Handle the device with care to avoid static discharge, which can damage the internal components.
   • Follow standard ESD (Electrostatic Discharge) precautions during handling and installation.
