NEXPERIA PCA9535PWJ I/O Expander, 16 bit, I2C, SMBus, 2.3 V, 5.5 V, TSSOP, 24 Pins

PCA9535PWJ is a low-voltage 16-bit 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 2.3V 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. The polarity inversion register can be programmed to invert the polarity of input register. It allows up-to eight devices to share the same I²C-bus/SMBus.
