NCA9534B - 8-bit I2C-bus I/O port
NCA9534B 8-bit I2C-bus I/O port with interrupt Datasheet (EN) 1.1 Product Overview The NCA9534B is a 16-pin device that provides 8 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 NCA9534B consists of an 8-bit Config
