MAX7317AEE+

The MAX7317AEE+ is a 10 port SPI-interfaced I/O expander with over voltage and hot insertion protection in 16 pin QSOP package. The serial interfaced peripheral provides microprocessors with 10 I/O ports rated to 7V. Each port can be individually configured as either an open-drain output or an over voltage protected schmitt input. It supports hot insertion, all port pins remain high impedance in power-down (V+ = 0V) with up to 8V asserted on them. It is used in white goods and cellular phones. .

• Supply voltage range is 2.25V to 3.6V
• Operating temperature range from -40°C to +125°C
• Standard 4-wire interface simplifies I/O ports expansion independent of microprocessor architecture
• High speed, 26MHz, SPI/QSPI/MICROWIRE compatible serial interface
• Protection circuitry ensures robust operation
• Low power consumption, small package reduce board size & power supply requirements
• Supply current of 620µA(max) at TA = +25°C, fSCLK = 26MHz
• Maximum output data propagation delay is 19ns
