4-Wire-Interfaced, 2.5V to 5.5V, 20-Port and 28-Port I/O Expande

 

 

General Description

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 MAX7301AGL have 28 ports and

are available in 36-pin SSOP and 40-pin QFN packages,

respectively. The MAX7301AAI and MAX7301ANI have

20 ports and are available in 28-pin SSOP and 28-pin DIP

packages, respectively.

For a 2-wire 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.
