Description and Introduction

18-Port GPIO with LED Intensity Control, Interrupt, and Hot-Insertion Protection The MAX7314ATG+T is a serial-interfaced peripheral manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX7314ATG+T  
- **Package:** 24-TQFN (4x4)  
- **Operating Voltage Range:** 1.65V to 5.5V  
- **Number of I/O Ports:** 16  
- **Interface:** I²C-compatible (up to 400kHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Output Current per I/O:** ±25mA  
- **Quiescent Current:** 1µA (standby mode)  

### **Descriptions:**  
The MAX7314ATG+T is a 16-bit I/O expander with an I²C-compatible serial interface. It provides general-purpose remote I/O expansion for most microcontroller families. Each of the 16 I/O ports can be independently configured as an input or output. The device includes internal pull-up resistors, reducing external component count.  

### **Features:**  
- **16 Programmable I/O Pins:** Each can be set as input or output.  
- **Low Standby Current:** 1µA in shutdown mode.  
- **Wide Voltage Operation:** Supports 1.65V to 5.5V.  
- **Internal Pull-Up Resistors:** Eliminates need for external resistors.  
- **High Output Drive:** ±25mA per I/O.  
- **Interrupt Output:** Indicates input port state changes.  
- **400kHz I²C Interface:** Fast communication with host MCU.  
- **Industrial Temperature Range:** -40°C to +125°C.  

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

Description and Introduction

18-Port GPIO with LED Intensity Control, Interrupt, and Hot-Insertion Protection The **MAX7314ATG+T** is a **16-bit I²C port expander with interrupt** from **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Package:** 24-TQFN (4x4mm)  
- **Operating Voltage:** **1.65V to 5.5V**  
- **Number of I/O Ports:** **16** (configurable as inputs or outputs)  
- **Interface:** **I²C-compatible** (up to **400kHz**)  
- **Interrupt Output:** Configurable for input state changes  
- **Current Consumption:** Low standby current  
- **Operating Temperature Range:** **-40°C to +125°C**  

### **Descriptions:**
- The MAX7314ATG+T is a **general-purpose I/O expander** that communicates via the **I²C bus**, allowing a microcontroller to control up to **16 GPIOs** with minimal wiring.  
- It features **interrupt capability**, notifying the host of input changes without continuous polling.  
- Each I/O pin is **independently configurable** as an input or output with **internal pull-up resistors**.  

### **Features:**
- **16 configurable GPIO pins** (individually programmable as inputs or outputs)  
- **I²C interface** (supports standard, fast, and high-speed modes)  
- **Interrupt output** for monitoring input changes  
- **Internal pull-up resistors** (eliminates external components)  
- **Wide voltage range** (1.65V to 5.5V) for compatibility with various logic levels  
- **Low-power operation** (suitable for battery-powered applications)  
- **Industrial temperature range** (-40°C to +125°C)  

This device is commonly used in **industrial control, consumer electronics, and embedded systems** for expanding I/O capabilities efficiently.
