Description and Introduction

I²C Port Expander with 12 Push-Pull Outputs and 4 Open-Drain I/Os The MAX7327AATG+ is a serial-interfaced peripheral from Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX7327AATG+  
- **Type:** I²C-Controlled 8-Channel GPIO Expander  
- **Package:** 24-Pin TQFN  
- **Operating Voltage:** 1.71V to 5.5V  
- **I/O Ports:** 8 (individually configurable as inputs or push-pull outputs)  
- **I²C Interface:** Supports 400kHz (fast mode)  
- **Interrupt Output:** Open-drain for monitoring input changes  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**
The MAX7327AATG+ is an I²C-controlled GPIO expander designed to add extra I/O ports to microcontrollers with limited pins. It features eight configurable GPIO pins, an interrupt output for input state monitoring, and operates across a wide voltage range, making it suitable for various applications.

### **Features:**
- **8 Configurable I/O Pins:** Each can be set as an input or push-pull output.  
- **Wide Voltage Range:** Operates from 1.71V to 5.5V, compatible with low-voltage systems.  
- **I²C Interface:** Supports up to 400kHz communication.  
- **Interrupt Output:** Alerts the host MCU of input changes.  
- **Low Standby Current:** Suitable for power-sensitive applications.  
- **Industrial Temperature Range:** -40°C to +125°C for harsh environments.
