Description and Introduction

16-Port I/O Expander with LED Intensity Control, Interrupt, and Hot-Insertion Protection The MAX7313ATG is a serial-interfaced I/O expander manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX7313ATG  
- **Package:** 24-pin TQFN (Thin Quad Flat No-Lead)  
- **Operating Voltage:** 2.5V to 5.5V  
- **Number of I/O Ports:** 16 (configurable as inputs or outputs)  
- **Interface:** I²C-compatible (400kHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Output Current per Pin:** 20mA (sink/source)  
- **Interrupt Output:** Yes (open-drain)  
- **Internal Pull-Up Resistors:** Configurable per port  

### **Descriptions:**  
The MAX7313ATG is a 16-bit I/O expander designed for applications requiring additional GPIOs controlled via an I²C interface. It is commonly used in embedded systems, industrial controls, and consumer electronics to expand microcontroller I/O capabilities.  

### **Features:**  
- **16 Programmable I/O Pins:** Each pin can be independently configured as an input or output.  
- **I²C-Compatible Serial Interface:** Supports standard (100kHz) and fast (400kHz) modes.  
- **Interrupt Output:** Notifies the host controller of input state changes.  
- **Internal Pull-Up Resistors:** Software-configurable for each I/O pin.  
- **High Drive Capability:** 20mA sink/source per I/O pin.  
- **Low Standby Current:** Suitable for power-sensitive applications.  
- **Wide Voltage Range:** Operates from 2.5V to 5.5V.  
- **Industrial Temperature Range:** -40°C to +125°C.
