Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 4.5V to 5.5V.
   • Connect a decoupling capacitor (0.1μF) close to the Vcc pin to filter out noise.

2. Input Signals:

   • The input voltage (VIN) should be within the range of 0V to 5V.
   • Avoid applying voltages outside this range to prevent damage to the device.

3. Output Configuration:

   • The output can sink or source up to 20mA.
   • Use appropriate external components (e.g., resistors) to limit current when driving LEDs or other loads.

4. Timing Considerations:

   • The propagation delay time (tpd) is typically 10ns, with a minimum of 5ns and a maximum of 15ns.
   • Account for this delay in your timing calculations to ensure proper operation.

5. Temperature Range:

   • The device is designed to operate within a temperature range of 0°C to 70°C.
   • Store the device within a temperature range of -40°C to 85°C.

6. Handling:

   • Handle the device with care to avoid static discharge.
   • Follow standard ESD (Electrostatic Discharge) precautions during assembly and handling.

7. Mounting:

   • Solder the device using a temperature-controlled soldering iron.
   • Ensure good thermal management if the device will be operating at higher temperatures.

8. Testing:

   • Verify the functionality of the device by testing the output voltages (VOH and VOL) under different input conditions.
   • Check the quiescent current (IQ) to ensure it is within the specified range.
