MAX7301ATL+

MAX7301ATL+ is a 4 wire interfaced, 2.5V to 5.5V, 28 port I/O expander in 40 pin TQFN package. This 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 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 pull-up. 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.

• Low power consumption reduces power supply requirements
• Operating temperature range from -40°C to 125°C
• High speed 26MHz SPI/QSP/MICROWIRE compatible serial interface
• Maximum shutdown current is 11μA
