Description and Introduction

18-Port GPIO with LED Intensity Control, Interrupt, and Hot-Insertion Protection The MAX7314AEG+ is an I²C-interfaced 16-bit I/O port expander manufactured by Maxim Integrated (now part of Analog Devices).  

### **Key Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 24-pin QSOP  
- **Operating Voltage:** 1.65V to 5.5V  
- **I/O Ports:** 16 configurable GPIOs (individually programmable as inputs or outputs)  
- **Interface:** I²C-compatible (up to 400kHz)  
- **Interrupt Output:** Configurable for input state change detection  
- **Current Consumption:** Low standby current (1µA typical)  
- **Output Drive Strength:** 10mA per I/O (sink/source)  
- **Temperature Range:** -40°C to +85°C  

### **Features:**  
- **Configurable I/O:** Each pin can be independently set as input or output.  
- **Internal Pull-Up Resistors:** Programmable per port.  
- **Interrupt on Change:** Detects input transitions and alerts the host via an interrupt pin.  
- **Software Reset:** Supports I²C software reset command.  
- **Small Footprint:** Suitable for space-constrained applications.  

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