RoHS: Unknown
View Datasheet Manufacturer Site View Pricing & Stock

The MAX7301 compact, serial-interfaced I/O expander (or general-purpose I/O (GPIO) peripheral) provides microprocessors with up to 28 ports. Each port is individually user configurable to either a logic input or logic output. Each port can be configured either as a push-pull logic output capable of sinking 10mA and sourcing 4.5mA, or a Schmitt logic input with optional internal pullup. Seven ports feature configurable transition detection logic, which generates an interrupt upon change of port logic level. The MAX7301 is controlled through an SPI-compatible 4-wire serial interface. The MAX7301AAX and MAX7301ATL have 28 ports and are available in 36-pin SSOP and 40-pin TQFN packages, respectively. The MAX7301AAI has 20 ports and is available in a 28-pin SSOP package. For a 2-wire I²C-interfaced version, refer to the MAX7300 data sheet. For a pin-compatible port expander with additional 24mA constant-current LED drive capability, refer to the MAX6957 data sheet.
