The TCA6424ARGJR is a low-voltage 24-bit I²C and SMBus I/O Expander 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 VCC range. It can operate on the P-port side and on the SDA/SCL side. This allows the TCA6424A 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 5V power supply.
