MAX7320 - I2C Port Expander

General Description

The MAX7320 2-wire serial-interfaced peripheral

Key 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).

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.
