Description and Introduction

I2C Port Expander with 8 Push-Pull and 8 Open-Drain I/Os The MAX7325ATG+ is a serial-interfaced peripheral manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX7325ATG+  
- **Type:** I²C/SMBus-Compatible 8-Channel GPIO Expander  
- **Operating Voltage:** 1.7V to 5.5V  
- **Number of I/O Ports:** 8 (configurable as inputs or outputs)  
- **Interface:** I²C/SMBus-Compatible (400kHz max)  
- **Output Current per Pin:** 25mA (sink/source)  
- **Package:** 24-Pin TQFN (5mm x 5mm)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The MAX7325ATG+ is an I²C/SMBus-compatible GPIO expander that provides 8 additional general-purpose I/O ports for microcontrollers or processors. It supports bidirectional voltage-level translation and features interrupt output for monitoring input changes.  

### **Features:**  
- **8 Configurable I/O Pins:** Can be independently set as inputs or outputs.  
- **Wide Voltage Range:** Operates from 1.7V to 5.5V, enabling compatibility with various logic levels.  
- **Interrupt Output:** Notifies the host of input changes without polling.  
- **Low Standby Current:** Consumes minimal power in standby mode.  
- **400kHz I²C Interface:** Supports fast communication.  
- **25mA Drive Capability per I/O:** Suitable for driving LEDs and small loads.  
- **Internal Pull-Up Resistors:** Simplifies external circuitry.  
- **Industrial Temperature Range:** Operates reliably in harsh environments (-40°C to +125°C).  

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