NCA9555-Q100 Low-voltage 16-bit I²C and SMBus I/O expander with interrupt output and configuration registers Rev. 3 — 24 April 2023 Product data sheet 1. General description The NCA9555-Q100 provides 16 bits of General Purpose Input/Output (GPIO) expansion for I²C-bus/SMBus applications. It is designed for a wide voltage range of 1.65 V to 5.5 V with interrupt and default pull-up resistors on GPIOs. Nexperia GPIO expanders provide an elegant solution when additional IOs are needed while keeping the interconnections to a minimum, for example, in ACPI power switches, sensors, push buttons, LEDs and fan control. The NCA9555-Q100 contains a set of 8 bit input, output, configuration and polarity inversion registers. At power up all IOs default to inputs.
