TCA6416 Description
This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed to provide general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL) and serial data (SDA)]. Not Remended for New Designs TCA6416 SCPS153B DECEMBER 2007 REVISED JUNE 2014 .ti.
TCA6416 Key Features
