NCA9535BY-Q100HP

NCA9535BY-Q100HP is a low-voltage 16-bit I²C and SMBus low-power I/O expander with interrupt output and configuration register. It provides 16 bits of general purpose I/P/O/P (GPIO) expansion for I²C-bus/SMBus applications. It is designed for a wide voltage range of 1.65V to 5.5V with interrupt. 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, sensor, push buttons, LEDs and fan control. It contains a set of 8-bit input, output, configuration and polarity inversion registers. At power up all IOs default to inputs. Each IO can be configured as either input or output by changing the corresponding bit in the configuration register. The data for each input or output is stored in the corresponding input or output register. The polarity inversion register can be programmed to invert the polarity of the input register.
