NCA9555B 16-bit I2C-bus I/O port

NCA9555B 16-bit I2C-bus I/O port with interrupt Datasheet (EN) 1.1 Product Overview The NCA9555B is a 24-pin device that provides 16 bits of General Purpose parallel Input/Output (GPIO) expansion for the two-line bidirectional I2C bus applications. The device can operate with a power supply voltage (VDD) range from 1.65 V to 5.5 V. It provides a simple solution when additional I/Os are needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc. The NCA9555B consists of two 8-bit Con.
