Fonctionnalités et applications

The PCA9539BS,118 is a part of PCA9539 is a 24-pin CMOS device that provides 16 bits of General Purpose parallel I/O (GPIO) expansion with interrupt and reset for I2C-bus/SMBus with a operating temprature between -40 °C to +85 °C and comes with HVQFN24 Package

I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc.
