Description and Introduction

18-Port GPIO with LED Intensity Control, Interrupt, and Hot-Insertion Protection The MAX7314ATG is a serial-interfaced peripheral manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX7314ATG  
- **Package:** 24-TQFN (4x4)  
- **Interface:** I²C-compatible serial interface  
- **Operating Voltage:** 2.3V to 5.5V  
- **Number of I/O Ports:** 16 (configurable as inputs or outputs)  
- **Maximum Output Current per I/O:** 20mA (sink/source)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Interrupt Output:** Yes (open-drain)  
- **Internal Pull-Up Resistors:** Programmable (100kΩ typical)  
- **Power-On Reset (POR):** Yes  

### **Descriptions:**  
The MAX7314ATG is a 16-bit I/O expander with an I²C-compatible serial interface. It provides general-purpose parallel input/output (GPIO) expansion for microcontrollers and other digital systems. The device supports programmable input/output configurations, internal pull-up resistors, and interrupt reporting for input state changes.  

### **Features:**  
- **16 configurable GPIO pins** (individually programmable as inputs or outputs)  
- **I²C-compatible serial interface** (up to 400kHz)  
- **2.3V to 5.5V supply voltage range**  
- **20mA sink/source capability per I/O**  
- **Interrupt output for input state monitoring**  
- **Programmable internal pull-up resistors**  
- **Power-on reset (POR) for default state initialization**  
- **Low standby current consumption**  
- **Industrial temperature range (-40°C to +125°C)**
