2-Wire-Interfaced, 2.5V to 5.5V, 20-Port or
28-Port I/O Expander
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 MAX7300ATL have 28 ports and
are available in 36-pin SSOP and 40-pin TQFN pack-
ages, respectively. The MAX7300AAI and MAX7300ATI
have 20 ports and are available in 28-pin SSOP and
TQFN packages. For an SPI-interfaced version, refer to
the MAX7301 data sheet. For a pin-compatible port
expander with additional 24mA constant-current LED
drive capability, refer to the MAX6956 data sheet.
