NCA9539-Q100 Overview
The NCA9539-Q100 provides 16 bits of General Purpose Input/Output (GPIO) expansion with interrupt and reset for I²C-bus/SMBus applications. It is designed for a wide voltage range of 1.65 V to 5.5 V. 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.
NCA9539-Q100 Key Features
