Part Details:

19-2413; Rev 6; 8/06 2-Wire-Interfaced, 2.5V to 5.5V, 20-Port or 28-Port I/O Expander MAX7300 General Description Features The MAX7300 compact, serial-interfaced, I/O expan- 400kbps I2C-Compatible Serial Interface sion peripheral provides microprocessors with up to 28 2.5V to 5.5V Operation ports. Each port is individually user configurable toeither a logic input or logic output. -40°C to +125°C Temperature Range Each port can be configured as either a push-pull logic 20 or 28 I/O Ports, Each Configurable as output capable of sinking 10mA and sourcing 4.5mA, or a Push-Pull Logic Output Schmitt logic input with optional internal pullup. Seven Schmitt Logic Input ports feature configurable transition detection logic, which Schmitt Logic Input with Internal Pullup generates an interrupt upon change of port logic level.The MAX7300 is controlled through an I2C*-compatible 2- 11µA (max) Shutdown Current wire serial interface, and uses four-level logic to allow 16 Logic Transition Detection for Seven I/O Ports I2C addresses from only two select pins. The MAX7300AAX and MAX7300ATL have 28 ports and Ordering Information are available in 36-pin SSOP and 40-pin thin QFN pack-ages, respectively. The MAX7300AAI and MAX7300ATI PIN- PKG PART TEMP RANGE have 20 ports and are available in 28-pin SSOP and thin PACKAGE CODE QFN packages. For an SPI-interfaced version, refer to MAX7300AAI -40°C to +125°C 28 SSOP A28-1 the MAX7301 data sheet. For a pin-compatible portexpander with additional 24mA constant-current LED MAX7300ATI** -40°C to +125°C 28 Thin QFN T2855-6 drive capability, refer to the MAX6956 data sheet.
