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.
