MAX7321AEE Product Details
General Description
The MAX7321AEE 2-wire serial-interfaced peripheral features eight open-drain I/O ports with selectable internal pullups and transition detection. Any port may be used as a logic input or an open-drain output. Ports are overvoltage protected to +6V independent of supply voltage.
All I/O ports configured as inputs are continuously monitored for state changes (transition detection). State changes are indicated by the open-drain INT output.The interrupt is latched, allowing detection of transient changes. When the MAX7321AEE is subsequently accessed through the serial interface, any pending interrupt is cleared.
The open-drain outputs are rated to sink 20mA and are capable of driving LEDs.
The RST input clears the serial interface, terminating any 12C communication to or from the MAX7321.
The MAX7321AEE uses two address inputs with four-level logic to allow 16 12C slave addresses. The slave address also determines the power-up logic state for the I/O ports, and enables or disables internal 40k2 pullups in groups of four ports.
The MAX7321AEE 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 MAX7321AEE is available in 16-pin QSOP and TQFN packages, and is specified over the automotive temperature range(-40°℃ to+125℃).
