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**

- •*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**
