Description and Introduction

8-Port I/O Expander with LED Intensity Control, Interrupt, and Hot-Insertion Protection The MAX7315ATE+T is a serial-interfaced peripheral manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX7315ATE+T  
- **Package:** 16-TQFN (3x3)  
- **Operating Voltage:** 2.3V to 5.5V  
- **Number of I/O Ports:** 16 (8 input, 8 push-pull output)  
- **Interface:** I²C-compatible (400kHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Interrupt Output:** Yes (for input change detection)  
- **Current Consumption:** Low power (typ. 1µA in shutdown)  

### **Descriptions:**  
The MAX7315ATE+T is an I²C-controlled I/O expander that provides 16 GPIO pins (8 configurable as inputs and 8 as push-pull outputs). It features an interrupt output to notify the host of input changes, reducing polling requirements. The device operates over a wide voltage range, making it suitable for battery-powered and industrial applications.  

### **Features:**  
- **16 GPIO Pins:** 8 inputs (with interrupt) and 8 push-pull outputs.  
- **I²C Interface:** Supports 400kHz communication.  
- **Wide Voltage Range:** 2.3V to 5.5V operation.  
- **Low Power Consumption:** 1µA (typ) in shutdown mode.  
- **Interrupt Output:** Flags input changes to the host.  
- **Industrial Temperature Range:** -40°C to +125°C.  
- **Small Package:** 16-TQFN (3x3mm) for space-constrained designs.  

This device is commonly used in system monitoring, industrial controls, and embedded applications requiring additional I/O expansion.
