(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
(3) The package thermal impedance is calculated in accordance with JESD 51-7.

Description

This TCA6416 16-bit I/O expander for the two-line bidirectional bus (I²C) is designed to provide general-purpose remote I/O xpansion for most microcontroller families via the I²C interface [serial clock (SCL) and serial data (SDA)].

The major benefit of this device is its wide V_CC range. TCA6416 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.
