DESCRIPTION/ORDERING INFORMATION  
This 24-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 VCC range. 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 TCA6424 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 TCA6424 is provided through VCCI. VCCI should be connected to  
the VCC of the external SCL/SDA lines. This indicates the VCC level of the I2C bus to the TCA6424. The voltage  
level on the P-port of the TCA6424 is determined by the VCCP  
.
