Description and Introduction

2-Wire-Interfaced 16-Bit I/O Port Expander with Interrupt and Hot-Insertion Protection The MAX7311ATG is a serial-interfaced peripheral manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX7311ATG  
- **Package:** 24-Pin TQFN  
- **Operating Voltage:** 2.5V to 5.5V  
- **Number of I/O Ports:** 16 (8 Inputs, 8 Push-Pull Outputs)  
- **Interface:** I²C-Compatible Serial Interface (400kHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Quiescent Current:** 1.5mA (Typical)  
- **Output Current per Pin:** 20mA (Sink/Source)  

### **Descriptions:**  
The MAX7311ATG is an I²C-controlled I/O expander designed to provide additional GPIO (General-Purpose Input/Output) ports for microcontrollers. It features 16 I/O pins, configurable as inputs or outputs, with programmable pull-ups and transition detection for inputs. The device operates over a wide voltage range, making it suitable for various applications requiring port expansion.

### **Features:**  
- **16 Programmable I/O Pins:**  
  - 8 pins can be configured as inputs with programmable pull-ups.  
  - 8 pins can be configured as push-pull outputs.  
- **I²C-Compatible Serial Interface:** Supports up to 400kHz communication.  
- **Interrupt Output:** Notifies the host of input state changes.  
- **Low Standby Current:** 1μA (Typical) in shutdown mode.  
- **Transition Detection:** Monitors input changes for event-driven applications.  
- **Wide Voltage Range:** Operates from 2.5V to 5.5V.  
- **Industrial Temperature Range:** -40°C to +125°C.  

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