NCA9595-Q100
description
The NCA9595-Q100 provides 16 bits of General Purpose Input/Output (GPIO) expansion for I²Cbus/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 NCA9595-Q100 contains a set of 8 bit input, output, configuration, polarity inversion and configuration pull-up 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 pull-up resistors can be disconnected by programming configuration pull...
