XL9555 - 16-bit I2C-bus and SMBus I/O port Expander

Download the XL9555 datasheet PDF. This datasheet also covers the XL9535 variant, as both devices belong to the same 16-bit i2c-bus and smbus i/o port expander family and are provided as variant models within a single manufacturer datasheet.

General Description

This device (XL9535/XL9555) is a 24-pin CMOS IC that provides 16-bit of General Purpose parallel Input/Output (GPIO) expansion for most micro-controller families via the I2C-bus/SMBus interface [serial clock line (SCL), serial data line (SDA)].

Key Features

XL9535, XL9555 Product datasheet XL9535, XL9555 16-bit I2C-bus and SMBus I/O port Expander With Interrupt Output and Configuration Registers Rev. 2.2 — 2018 1. DESCRIPTION This device (XL9535/XL9555) is a 24-pin CMOS IC that provides 16-bit of General Purpose parallel Input/Output (GPIO) expansion for most micro-controller families via the I2C-bus/SMBus interface [serial clock line (SCL), serial data line (SDA)]. These device is designed for 2.3-V to 5.5-V VCC operation. The improvements include higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O configuration, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc.
