Description and Introduction

2-Wire-Interfaced 16-Bit I/O Port Expander with Interrupt and Hot-Insertion Protection The MAX7311AAG is a serial-interfaced peripheral manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX7311AAG  
- **Type:** I²C-Interfaced 16-Bit I/O Expander  
- **Operating Voltage:** 2.3V to 5.5V  
- **Number of I/O Ports:** 16 (configurable as inputs or outputs)  
- **Interface:** I²C (400kHz fast-mode compatible)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin SSOP  

### **Descriptions:**
The MAX7311AAG is a 16-bit I/O expander with an I²C-compatible serial interface. It allows microcontrollers to expand their I/O capabilities by providing additional GPIO pins. Each of the 16 I/O ports can be independently configured as an input or output. The device includes internal pull-up resistors and supports interrupt outputs for efficient event monitoring.

### **Features:**
- **16 Configurable I/O Pins:** Each pin can be set as an input or output.  
- **I²C Interface:** Supports standard (100kHz) and fast (400kHz) modes.  
- **Internal Pull-Up Resistors:** Eliminates the need for external resistors.  
- **Interrupt Output:** Alerts the host controller of input changes.  
- **Low Standby Current:** Suitable for power-sensitive applications.  
- **Wide Voltage Range:** Operates from 2.3V to 5.5V.  
- **Industrial Temperature Range:** -40°C to +85°C.
