MAX7317ATE+ Datasheet PDF - Maxim Integrated

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.

● Industry-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

● I/O Port Inputs Are Overvoltage Protected to 7V

● I/O Port Outputs Are 7V-Rated Open Drain

● I/O Ports Support Hot Insertion
