Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the specified range of 4.5V to 5.5V.
   • Connect the ground (GND) pin to a stable 0V reference.

2. Input Signals:

   • Input signals should be within the valid input voltage levels:
     • High (V_IH): ≥ 2.0V
     • Low (V_IL): ≤ 0.8V

3. Output Signals:

   • The output high voltage (V_OH) will typically be around 3.5V but can range from 2.4V to the supply voltage.
   • The output low voltage (V_OL) will typically be around 0.4V but can range up to 0.5V.

4. Propagation Delay:

   • The propagation delay time (t_pd) is the time it takes for the output to change state after an input change. It ranges from 10ns to 20ns.

5. Temperature Considerations:

   • The device is designed to operate within the temperature range of -40°C to 85°C.
   • Store the device in an environment where the temperature does not exceed -65°C to 150°C.

6. Power Dissipation:

   • The maximum power dissipation (P_TOT) is 100mW. Ensure proper heat dissipation if operating near this limit.

7. Handling:

   • Handle the device with care to avoid damage from electrostatic discharge (ESD).
   • Follow standard ESD protection guidelines when handling and installing the device.

8. Mounting:

   • Solder the device according to the recommended soldering profile provided by the manufacturer.
   • Ensure good thermal and electrical connections to the PCB.

By following these parameters and instructions, you can ensure optimal performance and reliability of the SN74AS869NT.
