Instructions for Use:
Power Supply Connection: Ensure that the supply voltage is within the specified range of 4.5V to 5.5V. Connect VCC and GND pins appropriately.
Signal Integrity: For optimal performance, keep the trace lengths from the drivers to the load as short as possible to minimize signal degradation.
Decoupling Capacitors: Place decoupling capacitors close to the power pins to reduce noise and improve transient response.
Heat Management: Although the device can operate up to 85°C ambient temperature, ensure adequate ventilation or heat sinking if operating near this limit.
Input Signals: Ensure input signals are within the valid logic levels for reliable operation. Inputs should not exceed VCC or go below GND.
Output Loading: The device can drive peak currents up to 250mA per channel. Avoid exceeding this limit to prevent damage.
Storage Conditions: When storing the device, maintain temperatures between -65°C and 150°C to avoid damage.
Handling Precautions: Handle with care to avoid static damage. Follow ESD protection guidelines during installation and handling.
Mounting: Ensure proper mounting on the PCB to avoid mechanical stress on the package which could affect reliability.
Testing: After installation, test the functionality under expected operating conditions to confirm correct operation.
