Description and Introduction

Low-Voltage 24-Bit I2C and SMBus I/O Expander 32-UQFN -40 to 85 The TCA6424ARGJR is a 24-bit I²C and SMBus I/O expander manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Interface:** I²C, SMBus compatible  
- **Number of I/O Ports:** 24 (3 ports of 8 bits each)  
- **Supply Voltage Range:** 1.65V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **I²C Clock Frequency:** Up to 400 kHz  
- **Interrupt Output:** Configurable for any input change  
- **Low Standby Current:** < 1 µA (typical)  
- **Package:** 32-VQFN (5mm x 5mm)  

### **Descriptions:**
The TCA6424ARGJR is a low-voltage, bidirectional I/O expander designed for general-purpose I²C/SMBus applications. It provides 24 GPIO pins that can be individually configured as inputs or outputs. The device supports interrupt functionality, allowing the host controller to monitor input changes efficiently without continuous polling.

### **Features:**
- **24 Configurable GPIO Pins:** Each pin can be independently set as input or output.  
- **Wide Voltage Range:** Operates from 1.65V to 5.5V, making it compatible with various logic levels.  
- **Interrupt Output:** Pin-change detection triggers an interrupt to the host.  
- **Internal Power-On Reset:** Ensures proper initialization at power-up.  
- **Schmitt-Trigger Inputs:** Enhances noise immunity on input signals.  
- **Latched Outputs with High Current Drive:** Supports up to 25 mA sink capability per I/O.  
- **I²C Address Selection:** Three hardware-selectable address pins allow up to eight devices on the same bus.
