General Description
The MAX7300 compact, serial-interfaced, I/O expan-
sion 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 as either 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 MAX7300 is controlled through an I
2
C-compatible
2-wire serial interface, and uses four-level logic to allow
16 I
2
C addresses from only two select pins.
The MAX7300AAX and MAX7300AGL have 28 ports
and are available in 36-pin SSOP and 40-pin QFN pack-
ages, respectively. The MAX7300AAI and MAX7300ANI
have 20 ports and are available in 28-pin SSOP and 28-
pin DIP packages, respectively.
