MAX7317ATE+

MAX7317ATE+ is a 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. Suitable for portable equipment, cellular phones, white goods, industrial controllers and system monitoring applications.

• Industry-standard 4-wire interface simplifies I/O ports expansion independent of MPU architecture
• High-speed, 26MHz, SPI-/QSPI™-/MICROWIRE®- compatible serial interface
• 2.25V to 3.6V operation
• 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
• 2V min power-on reset voltage and 38.4ns min SCLK clock period
• 16 pin TQFN-EP package (3mm x 3mm x 0.8mm)
• Temperature range from -40°C to 125°C
