Description and Introduction

2-Wire-Interfaced 16-Bit I/O Port Expander with Interrupt and Hot-Insertion Protection The **MAX7311AUG+T** is a 16-bit I/O expander manufactured by **Maxim Integrated (now part of Analog Devices)**. Below are its key specifications, descriptions, and features based on factual data:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Category:** Interface - I/O Expanders  
- **Package:** 24-TSSOP  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** 1.65V to 5.5V  
- **Number of I/O Ports:** 16  
- **Interface Type:** I²C, SMBus  
- **Clock Frequency:** Up to 400kHz  
- **Interrupt Output:** Yes  
- **Current Consumption (Standby):** 1µA (typical)  

### **Descriptions:**  
The MAX7311AUG+T is a low-voltage, 16-bit I²C/SMBus I/O expander with interrupt output and internal pull-up resistors. It provides remote I/O expansion for microcontrollers via the I²C serial interface. Each of the 16 I/O pins can be independently configured as an input or output.  

### **Features:**  
- **16 Programmable I/O Pins:** Configurable as inputs or outputs.  
- **Wide Voltage Range:** Operates from **1.65V to 5.5V**, compatible with low-voltage systems.  
- **I²C/SMBus Interface:** Supports standard (100kHz) and fast (400kHz) modes.  
- **Interrupt Output:** Alerts the host of input changes without polling.  
- **Internal Pull-Up Resistors:** Eliminates the need for external resistors.  
- **Low Standby Current:** 1µA (typical) for power-sensitive applications.  
- **Industrial Temperature Range:** -40°C to +85°C.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Description and Introduction

2-Wire-Interfaced 16-Bit I/O Port Expander with Interrupt and Hot-Insertion Protection The MAX7311AUG+T is a serial-interfaced peripheral designed for I/O port expansion. Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
MAX (Maxim Integrated)

### **Specifications:**  
- **Interface Type:** I²C  
- **Number of I/O Ports:** 8  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-TSSOP  

### **Descriptions:**  
The MAX7311AUG+T is an I²C-compatible I/O expander that provides 8 general-purpose I/O ports. It is designed for applications requiring additional I/O lines controlled via a serial interface. The device supports both input and output configurations with programmable polarity inversion.

### **Features:**  
- **8 Configurable I/O Ports** (can be individually set as inputs or outputs)  
- **I²C Serial Interface** (supports standard, fast, and high-speed modes)  
- **Programmable Polarity Inversion** (for input ports)  
- **Low Standby Current** (suitable for battery-powered applications)  
- **Internal Power-On Reset** (initializes registers at power-up)  
- **Schmitt-Trigger Inputs** (for noise immunity)  
- **Open-Drain Outputs** (with 25mA sink capability per I/O)  

This device is commonly used in embedded systems, industrial controls, and consumer electronics for expanding microcontroller I/O capabilities.
