Product Description

**DESCRIPTION**
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.
**1****FEATURES**
•*Operating Power-Supply Voltage Range of ****1.65 V to 5.5 V**
•*Allows Bidirectional Voltage-Level Translation ****and GPIO Expansion Between:**
**– 1.8-V SCL/SDA and ****1.8-V, 2.5-V, 3.3-V, or 5-V P Port**
**– 2.5-V SCL/SDA and ****1.8-V, 2.5-V, 3.3-V, or 5-V P Port**
**– 3.3-V SCL/SDA and ****1.8-V, 2.5-V, 3.3-V, or 5-V P Port**
**– 5-V SCL/SDA and ****1.8-V, 2.5-V, 3.3-V, or 5-V P Port**
•*I2C to Parallel Port Expander**
•*Low Standby Current Consumption of 1 **µ**A**
•*Schmitt-Trigger Action Allows Slow Input ****Transition and Better Switching Noise ****Immunity at the SCL and SDA Inputs**
