Maxim Integrated (MAX7301ATL+) I/O Expander, 26 MHz

Product Overview The 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 Applications Power Management, Portable Devices, Industrial, System Monitoring Product Information Chip Configuration: - Bus Frequency: 26MHz IC Interface Type: SPI Supply Voltage Min: 2.5V Supply Voltage Max: 5.5V Interface Case Style: TQFN No. of Pins: 40Pins No. of I/O's: 28I/O's Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
