MAX7320AEE+ by Analog Devices

I²C Port Expander with Eight Push-Pull Outputs


The MAX7320 2-wire serial-interfaced peripheral features eight push-pull outputs with selectable power-up logic states. The +5.5V tolerant active-low 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 active-low RST remain high impedance in power-down (V+ = 0V) with up to +6V asserted on them. The MAX7320 is one device in a family of pin-compatible port expanders with a choice of input ports, open-drain I/O ports, and push-pull output ports. The MAX7320 is available in 16-pin QSOP and 16-pin TQFN packages, and is specified over the automotive temperature range (-40°C to +125°C).
