Description and Introduction

2-Wire-Interfaced 16-Bit I/O Port Expander with Interrupt and Hot-Insertion Protection The MAX7312AUG+ is a serial-interfaced I/O expander manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

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

### **Specifications:**  
- **Part Number:** MAX7312AUG+  
- **Type:** I²C/SMBus-Compatible 8-Bit I/O Expander  
- **Operating Voltage:** 1.8V to 5.5V  
- **Number of I/O Ports:** 8 (configurable as inputs or outputs)  
- **Interface:** I²C/SMBus-Compatible (up to 400kHz)  
- **Package:** 24-TSSOP  
- **Operating Temperature Range:** -40°C to +85°C  
- **Interrupt Output:** Yes (for input change detection)  
- **Internal Pull-Up Resistors:** Yes (100kΩ typical)  
- **Output Drive Strength:** 10mA per I/O (sink/source)  

### **Descriptions:**  
The MAX7312AUG+ is an I/O expander designed to provide additional GPIO ports for microcontrollers via the I²C/SMBus interface. It features eight configurable I/O pins that can be independently set as inputs or outputs. The device includes interrupt capability to notify the host of input changes, reducing polling requirements.  

### **Features:**  
- **Wide Voltage Range:** Supports operation from 1.8V to 5.5V  
- **Configurable I/O Pins:** Each of the 8 I/Os can be independently set as input or output  
- **Interrupt Output:** Alerts the host of input changes  
- **Internal Pull-Up Resistors:** Eliminates the need for external resistors  
- **Low Standby Current:** Suitable for power-sensitive applications  
- **Small Package:** 24-TSSOP for space-constrained designs  

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