STMicroelectronics recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
To ensure reliable operation at high temperatures, it's essential to follow the recommended thermal design guidelines, use a suitable thermal interface material, and consider derating the device's power dissipation according to the temperature derating curve provided in the datasheet.
The maximum allowed voltage on the input pins is 5.5V, which is the absolute maximum rating. However, for reliable operation, it's recommended to keep the input voltage within the recommended operating range of 3.3V to 5V.
The RHRXH162245K1 has built-in ESD protection, but it's still recommended to follow proper ESD handling procedures during assembly and testing. Additionally, consider adding external ESD protection devices if the device will be exposed to harsh environments.
The recommended power-up sequence is to apply the power supply voltage (VCC) before applying any input signals. This ensures that the internal voltage regulators and bias circuits are properly initialized before the device starts operating.
