Description and Introduction

I2C Port Expander with 8 Push-Pull and 8 Open-Drain I/Os The MAX7325ATG+T is a serial-interfaced peripheral manufactured by Maxim Integrated. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX7325ATG+T  
- **Type:** I²C-Controlled 8-Bit I/O Expander  
- **Operating Voltage:** 1.71V to 5.5V  
- **Number of I/O Ports:** 8 (individually configurable as inputs or push-pull outputs)  
- **Maximum Output Current per Pin:** 25mA (sink/source)  
- **Maximum Total Current:** 200mA  
- **Interface:** I²C (400kHz fast-mode compatible)  
- **Package:** 24-Pin TQFN (5mm x 5mm)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The MAX7325ATG+T is an I²C-controlled I/O expander that provides 8 configurable GPIO ports. It is designed for applications requiring additional I/O pins controlled via an I²C interface. It supports both input and output configurations with internal pull-up resistors and features high current drive capability.  

### **Features:**  
- **Wide Voltage Range:** Operates from 1.71V to 5.5V, making it compatible with low-voltage processors.  
- **Configurable I/O Ports:** Each of the 8 I/O pins can be independently set as an input or output.  
- **Internal Pull-Up Resistors:** Simplifies input interfacing.  
- **High Current Drive:** Up to 25mA per pin (200mA total).  
- **I²C Interface:** Supports standard (100kHz) and fast-mode (400kHz) I²C communication.  
- **Interrupt Output:** Provides a pin to indicate input state changes.  
- **Low Standby Current:** Consumes minimal power in idle mode.  
- **Robust ESD Protection:** ±15kV Human Body Model (HBM) protection.  

This device is commonly used in industrial controls, consumer electronics, and embedded systems requiring additional I/O expansion.
