NCA9555 16-bit I2C-bus I/O port with interrupt Datasheet (EN) 1.4 Product Overview The NCA9555 is a 24-pin CMOS device that provides 16 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus applications. It provides a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc. The NCA9555 consists of two 8-bit Configuration (Input or Output selection); Input, Output and Polarity Inversion (active HIGH or active LOW operatio.

NCA9555 Features

* Operating power supply voltage range of 2.3 V to 5.5 V

* 5 V tolerant I/Os

* I2C to Parallel Port Expander

* Polarity Inversion register

* Active LOW interrupt output

* Compatible With Most Microcontrollers

* Address by Three Hardware Address Pins for Use of up to Eight
