Description and Introduction

10-Port SPI-Interfaced I/O Expander with Overvoltage and Hot-Insertion Protection The MAX7317AEE+T is a 2-wire serial-interfaced peripheral manufactured by Maxim Integrated. It features 16 I/O ports with selectable input/output configuration.  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 16-QSOP  
- **Interface:** 2-wire (I²C-compatible) serial  
- **Operating Voltage:** 1.65V to 5.5V  
- **I/O Ports:** 16 (individually configurable as input or output)  
- **Maximum Output Current:** 25mA per port  
- **Interrupt Output:** Configurable for port state change detection  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions and Features:**  
- **Configurable I/O Ports:** Each of the 16 I/O pins can be independently set as an input or output.  
- **Low Standby Current:** Suitable for power-sensitive applications.  
- **Internal Pull-Up Resistors:** Configurable for input ports.  
- **Interrupt Function:** Detects changes on input ports and signals the host via an interrupt pin.  
- **Wide Voltage Range:** Supports operation from 1.65V to 5.5V, making it compatible with various logic levels.  
- **High Drive Capability:** Each output can sink or source up to 25mA.  
- **Small Form Factor:** 16-QSOP package for space-constrained designs.  

This device is commonly used in applications requiring multiple configurable I/Os with a simple serial interface, such as industrial controls, consumer electronics, and embedded systems.
