Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 4.5V to 55V.
   • Connect V_CC to the positive power supply and GND to the ground.

2. Input Signals:

   • Apply a high-level input voltage (V_IH) of at least 2.0V to activate the Darlington pair.
   • Apply a low-level input voltage (V_IL) of no more than 0.8V to deactivate the Darlington pair.
   • Ensure the input current (I_IN) does not exceed 1.6 mA when V_IL is applied.

3. Output Current:

   • The maximum continuous output current (I_C) is 500 mA at 25°C.
   • For peak currents, the device can handle up to 600 mA with a pulse width of 1 ms and a duty cycle of 1%.

4. Saturation Voltages:

   • Monitor the collector-emitter saturation voltage (V_CE(sat)) to ensure it does not exceed 1.2V when the output current is 500 mA.
   • The base-emitter saturation voltage (V_BE(sat)) should be around 1.8V under typical operating conditions.

5. Leakage Current:

   • The leakage current (I_CEO) should be less than 100 nA at 50V and 25°C.

6. Temperature Considerations:

   • Store the device in a temperature range of -65°C to 150°C.
   • Operate the device within the temperature range of -40°C to 105°C to ensure reliable performance.

7. Handling and Storage:

   • Handle the device with care to avoid static damage.
   • Store in a dry, cool place to prevent moisture damage.

8. Circuit Design:

   • Use appropriate decoupling capacitors near the power supply pins to reduce noise and improve stability.
   • Ensure proper heat dissipation if operating at high currents or temperatures.
