Detailed description

 MAX7301AAX

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.
