Instructions for Using ULN2004AN:

1. Power Supply:

   • Connect the V_CC pin to the positive supply voltage (4.5V to 36V).
   • Connect the GND pin to the common ground.

2. Input Signals:

   • Apply logic high (V_IH) to the input pins (1-7) to turn on the corresponding Darlington transistor.
   • Apply logic low (V_IL) to the input pins to turn off the corresponding Darlington transistor.

3. Output Connections:

   • Connect the load between the output pins (18-11) and the positive supply voltage.
   • Ensure that the load current does not exceed the continuous output current rating (500mA per channel).

4. Protection:

   • Use external flyback diodes for inductive loads to protect the transistors from voltage spikes.
   • Ensure proper heat dissipation if operating at high currents or temperatures.

5. Common Emitter Configuration:

   • The ULN2004AN is designed for common emitter configuration, where the emitter of each Darlington pair is connected internally to the common ground.

6. Temperature Considerations:

   • Operate within the specified temperature range (-40掳C to 100掳C) to ensure reliable performance.
   • Store the device within the storage temperature range (-65掳C to 150掳C).

7. Handling Precautions:

   • Handle with care to avoid static damage.
   • Follow standard ESD (Electrostatic Discharge) precautions when handling the device.

By following these guidelines, you can effectively use the ULN2004AN in your electronic projects.
