Description

General part information

TCA6416 Series

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)].

The major benefit of this device is its wide VCCrange. It can operate from 1.65 V to 5.5 V on the P-port side and on the SDA/SCL side. This allows the TCA6416 to interface with next-generation microprocessors and microcontrollers on the SDA/SCL side, where supply levels are dropping down to conserve power. In contrast to the dropping power supplies of microprocessors and microcontrollers, some PCB components, such as LEDs, remain at a 5-V power supply.

The bidirectional voltage level translation in the TCA6416 is provided through VCCI. VCCIshould be connected to the VCCof the external SCL/SDA lines. This indicates the VCClevel of the I2C bus to the TCA6416. The voltage level on the P-port of the TCA6416 is determined by the VCCP.
