The recommended operating temperature range for the U4468B is -40°C to +125°C, although it can withstand storage temperatures from -55°C to +150°C.
The U4468B requires a single 5V power supply, and it's essential to decouple the power pins with a 10nF to 100nF capacitor to prevent noise and oscillations.
The U4468B can operate with clock frequencies up to 2MHz, but it's recommended to use a clock frequency of 1MHz or less for optimal performance and stability.
The U4468B can be interfaced with a microcontroller using a 3-wire serial interface (SCL, SDA, and RST). The microcontroller should provide the clock signal, and the U4468B will respond with data on the SDA line.
The RST (Reset) pin is used to reset the U4468B to its initial state. It's an active-low input, and when pulled low, it resets the device and clears all internal registers.
