Nexperia I2C expanders

Our NCA95xx family of General-Purpose I/O (GPIO) expanders provides an elegant solution when additional I/Os are needed while keeping the interconnections to a minimum. Features include interrupt, Hardware RESET, Internal pull-up resistors, and configurable pull-ups. These GPIO expanders benefits include extremely low static power consumptions and reduces the PCB design complexity through trace reduction and routing simplification thereby reducing the BOM cost.

Key features

• Low standby current consumption: 2.5 µA (maximum)
• Schmitt-trigger action allows slow input transition and better switching noise immunity
• Including a register configurable internal pull-up resistor.
• Reduced output capacitance of 4.5 pF

Additional features

• I²C-bus to parallel port expander
• Operating power supply voltage range of 1.65 V to 5.5 V
• Low standby current consumption:
• 2.5 µA (maximum)
