Instructions for Use:

1. Power Supply:

   • Connect the supply voltage (Vcc) to Pins 1 and 8.
   • Connect the ground (GND) to Pins 4 and 5.

2. Input Signals:

   • Apply the control signals to Pins 2 (IN1) and 7 (IN2). These signals should be within the range of 0V to 5V.
   • A high signal (typically 5V) will turn on the corresponding output, while a low signal (0V) will turn it off.

3. Output Connections:

   • Connect the load or MOSFET gate to Pins 3 (OUT1) and 6 (OUT2).
   • Ensure that the load current does not exceed the maximum output current rating of ±1A (peak).

4. Thermal Considerations:

   • The device can operate within a temperature range of -40°C to +85°C.
   • For high-power applications, consider using a heat sink to dissipate excess heat.

5. Protection:

   • The device includes built-in protection against overvoltage, overcurrent, and thermal overload.
   • However, it is recommended to use external protection circuits (e.g., fuses, diodes) for critical applications.

6. Storage and Handling:

   • Store the device in a dry, cool place away from direct sunlight.
   • Handle with care to avoid static damage. Use proper ESD (Electrostatic Discharge) precautions.
