Description and Introduction

Low-Voltage 16-Bit I2C and SMBus I/O Expander With Interrupt Output, Reset, and Config Registers 24-WQFN -40 to 85 The TCA6416RTWR is a 16-bit I²C and SMBus I/O expander manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Interface:** I²C, SMBus compatible  
- **Number of I/O Pins:** 16 (configurable as inputs or outputs)  
- **Operating Voltage:** 1.65V to 5.5V  
- **I²C Clock Frequency:** Up to 400 kHz  
- **Interrupt Output:** Configurable for active-low interrupt signaling  
- **Package:** 24-pin WQFN (RTW)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The TCA6416RTWR provides general-purpose remote I/O expansion via the I²C/SMBus interface.  
- It is designed for applications requiring additional I/O pins beyond what a microcontroller offers.  
- The device supports input/output configuration, polarity inversion, and interrupt monitoring for efficient system control.  

### **Features:**
- **16 Configurable GPIO Pins:** Each pin can be independently set as input or output.  
- **Low Standby Current:** Optimized for power-sensitive applications.  
- **Internal Power-On Reset:** Ensures default state at power-up.  
- **Programmable Pull-Up/Pull-Down Resistors:** Enhances flexibility in circuit design.  
- **Noise Filter on SCL/SDA Inputs:** Improves signal integrity.  
- **Latch-Up Performance Exceeds 100mA per JESD 78:** Ensures robustness.
