Description and Introduction

16-Port I/O Expander with LED Intensity Control, Interrupt, and Hot-Insertion Protection The MAX7313DATG+ is a serial-interfaced I/O expander manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
Maxim Integrated (now part of Analog Devices)  

### **Specifications:**  
- **Part Number:** MAX7313DATG+  
- **Package:** 24-Pin TSSOP  
- **Operating Voltage:** 1.8V to 5.5V  
- **Number of I/O Ports:** 16 (8 configurable as inputs or outputs)  
- **Interface:** I²C-compatible (up to 400kHz)  
- **Output Current:** 25mA per I/O (sink/source)  
- **Interrupt Output:** Yes (for input state change detection)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The MAX7313DATG+ is a low-voltage I²C/SMBus-compatible I/O expander designed to provide additional GPIO ports for microcontrollers. It features programmable input/output configurations, interrupt generation, and internal pull-up resistors.  

### **Features:**  
- **16 I/O Pins:** 8 pins can be independently configured as inputs or outputs.  
- **I²C Interface:** Supports standard (100kHz) and fast (400kHz) modes.  
- **Interrupt Output:** Alerts the host of input changes.  
- **Low Standby Current:** Suitable for power-sensitive applications.  
- **Internal Pull-Up Resistors:** Eliminates the need for external resistors.  
- **Wide Voltage Range:** Operates from 1.8V to 5.5V.  

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

Application Scenarios & Design Considerations

16-Port I/O Expander with LED Intensity Control, Interrupt, and Hot-Insertion Protection

Alternative Part Number

  • PCA9535PW,112 --: 16-bit I2C GPIO expander with similar functionality and pin-compatible TSSOP package, widely available and cost-effective.
  • TCA9535PWR --: 16-bit I2C/SMBus I/O expander with interrupt output, direct functional equivalent to MAX7313 in TSSOP.
  • PCF8575TS/1,112 --: 16-bit I2C I/O expander with open-drain outputs, suitable drop-in alternative for LED driving and GPIO expansion applications.
  • PCA9555PW,112 --: 16-bit I2C I/O expander with interrupt, functionally equivalent to the MAX7313 16-port expander; widely available and pin-compatible in function.
  • TCA9555PWR --: 16-bit I2C/SMBus I/O expander with interrupt output, direct functional replacement for MAX7313 in most designs.
