Maxim Integrated (MAX7317AEE+) I/O Expander, 26 MHz

Product Overview 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 Applications System Monitoring, Industrial, Portable Devices Product Information Chip Configuration: - Bus Frequency: 26MHz IC Interface Type: SPI Supply Voltage Min: 2.25V Supply Voltage Max: 3.6V Interface Case Style: QSOP No. of Pins: 16Pins No. of I/O's: 10I/O's Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
