PCA8575DB Overview
In order for the device to function, 24 pins must be used. It is made possible by the maximum operating temperature of 85 °C°C, enabling stable operation. To ensure reliability, it requires a minimum temperature of -40 °C degrees Celsius. Despite a supply voltage of 5.5 VV, it can withstand it. There is no need to worry about the source voltage of 2.3 V since the device can work with a low voltage.
