Low-voltage 16-bit I2C and SMBus low-power I/O expander with interrupt output and configuration registers
The NCA9535 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. 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 NCA9535 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. The NCA9535 has an open-drain interrupt output which is activated when any one of the GPIO changes from its corresponding input port register state. The power on reset sets the registers to default values and initializes the device state machine. The NCA9535 has three address pins A0, A1 and A2 which can be used to configure the I2C bus slave address of the device. It allows up-to eight devices to share the same I2C-bus/SMBus.

How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
