Instructions for Use

1. Power Supply:

   • The SN75492J can operate with a supply voltage (V_CC) ranging from 5V to 30V. Ensure that the supply voltage is within this range to avoid damage to the device.

2. Output Current:

   • Each channel can handle a continuous output current (I_O) of up to 1.5A. For short pulses (≤ 50 μs), the peak output current (I_OPK) can be as high as 6.0A.
   • The total output current (I_TOT) across all channels should not exceed 5.0A.

3. Input Logic Levels:

   • The input voltage high (V_IH) should be between 2.0V and 30V for the input to be recognized as high.
   • The input voltage low (V_IL) should be between 0V and 0.8V for the input to be recognized as low.

4. Input Current:

   • The input current high (I_IH) is typically 10 μA at V_I = 5V.
   • The input current low (I_IL) is typically 1.0 μA at V_I = 0V.

5. Output Voltage (Saturation):

   • When the output is saturated (V_CE(sat)), the voltage drop across the Darlington pair is typically 1.7V to 2.5V at an output current of 1.5A.

6. Power Dissipation:

   • The power dissipation per package (P_D) should not exceed 45W. Ensure adequate heat sinking if operating near this limit.

7. Temperature Ranges:

   • The operating temperature range (T_A) is from -40°C to 105°C.
   • The storage temperature range (T_STG) is from -65°C to 150°C.

8. Handling and Storage:

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

By following these parameters and instructions, you can ensure reliable operation of the SN75492J in your application.
