MAX7320
EVALUATION KIT AVAILABLE
I2C Port Expander with Eight Push-Pull Outputs
General Description
The MAX7320 2-wire serial-interfaced peripheral features eight push-pull outputs with selectable power-up logic states.
The +5.5V tolerant RST 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, AD2, and RST remain high impedance in power-down (V+ = 0V) with up to +6V asserted on them.
