Product Summary

The MAX7317AEE+ serial-interfaced peripheral provides microprocessors with 10 I/O ports rated to 7V. Each port can be individually configured as either an opendrain output, or an overvoltage-protected Schmitt input. The MAX7317AEE+ supports hot insertion. All port pins remain high impedance in power-down (V+ = 0V) with up to 8V asserted on them. The MAX7317AEE+ is available in 16-pin thin QFN and QSOP packages and operates in the -40℃ to +125℃ range.
