MAX7317AEE+ 10-Port SPI-Interfaced I/O Expander with Overvoltage and Hot-Insertion Protection SSOP16 spot stock

Product Descriptions

The MAX7317 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 overvoltage-protected Schmitt input.

The MAX7317 supports hot insertion. All port pins remain  high impedance in power-down (V+ = 0V) with up to 8V  asserted on them.

The MAX7317 is available in 16-pin TQFN and QSOP  packages and operates in the -40°C to +125°C range.

For a similar part with constant-current outputs and  8-bit PWM controls, refer to the MAX6966/MAX6967 data  sheet.
