Description and Introduction

10-Port SPI-Interfaced I/O Expander with Overvoltage and Hot-Insertion Protection The MAX7317AEE+ is a part manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX7317AEE+  
- **Type:** I²C-Controlled 16-Bit I/O Expander  
- **Package:** 16-QSOP  
- **Operating Voltage:** 1.65V to 5.5V  
- **Number of I/O Ports:** 16 (configurable as inputs or outputs)  
- **Interface:** I²C-compatible (up to 400kHz)  
- **Input/Output Logic Levels:** 1.8V to 5.5V compatible  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX7317AEE+ is a 16-bit I/O expander with an I²C-compatible serial interface. It allows microcontrollers with limited I/O pins to expand their capabilities by providing additional configurable GPIOs. Each of the 16 I/O ports can be independently configured as an input or output.  

### **Features:**  
- **16 Programmable I/O Pins:** Each pin can be configured as an input or output.  
- **Wide Voltage Range:** Operates from 1.65V to 5.5V, making it compatible with various logic levels.  
- **I²C Interface:** Supports standard (100kHz) and fast (400kHz) modes.  
- **Internal Pull-Up Resistors:** Configurable for input ports.  
- **Interrupt Output:** Notifies the host of input changes.  
- **Low Standby Current:** Suitable for power-sensitive applications.  
- **Small Package:** 16-QSOP for space-constrained designs.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Description and Introduction

10-Port SPI-Interfaced I/O Expander with Overvoltage and Hot-Insertion Protection The MAX7317AEE+ is a 16-port I²C GPIO expander manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Interface:** I²C-compatible (supports 400kHz fast-mode)  
- **Number of GPIO Ports:** 16 (configurable as inputs or outputs)  
- **Operating Voltage:** 1.65V to 5.5V  
- **Output Current:** 20mA per I/O (max)  
- **Input Voltage Range:** -0.5V to +6V (absolute max)  
- **Package:** 16-pin QSOP  
- **Operating Temperature Range:** -40°C to +85°C  
- **Interrupt Output:** Configurable for input state change detection  
- **Internal Pull-Up Resistors:** Programmable per port  

### **Descriptions & Features:**  
- **Bidirectional I/O Ports:** Each of the 16 GPIOs can be independently configured as an input or output.  
- **Interrupt on Change:** Detects transitions on input ports and generates an interrupt.  
- **Low Standby Current:** Suitable for battery-powered applications.  
- **Software Reset:** Supports I²C software reset command.  
- **Programmable Pull-Up Resistors:** Each input can have an internal pull-up resistor enabled.  
- **Open-Drain Outputs:** Supports open-drain configuration for outputs.  
- **Address Selection:** Three address pins allow up to eight devices on the same I²C bus.  

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