The MAX7320AEE+ is an I2C port expander with eight push-pull outputs in 16 pin QSOP package. It is a 2 wire serial-interfaced peripheral features eight push-pull outputs with selectable power-up logic states. The +5.5V tolerant reset input clears the serial interface, terminating any I2C communication to or from the MAX7320. The MAX7320 uses two address inputs with four-level logic to allow 16 I2C slave addresses. The slave address also determines the power-up state level for the outputs in groups of four ports. The MAX7320 supports hot insertion. The serial interface SDA, SCL, AD0, AD2and RST remain high impedance in power-down mode (V+ = 0V) with up to +6V asserted on it.
Supply voltage range is 1.71V to 5.5V
Operating temperature range from -40°C to 125°C
400KHz I2C serial interface 5.5V tolerant
Sink current is 100mA and source current is 50mA from all eight combined outputs
