NEXPERIA NCA9535PWJ I/O Expander, 16 bit, I2C, SMBus, 1.65 V, 5.5 V, TSSOP, 24 Pins

NCA9535PWJ is a low-voltage 16bit I²C and SMBus low-power I/O expander with interrupt output and configuration registers. It provides 16bits of general purpose input/output (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 expander provides 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. It contains a set of 8bit 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. It has an open-drain interrupt output which is activated when any one of the GPIO changes from its corresponding input port register state.
