Description and Introduction

I²C Port Expander with Eight Push-Pull Outputs and Eight Inputs The **MAX7324AEG+** is a serial-interfaced peripheral manufactured by **Maxim Integrated** (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
- **Maxim Integrated** (acquired by Analog Devices)  

### **Specifications:**  
- **Part Number:** MAX7324AEG+  
- **Type:** I²C-Controlled 8-Bit GPIO Expander  
- **Operating Voltage:** 1.71V to 5.5V  
- **Number of I/O Ports:** 8 (individually configurable as inputs or outputs)  
- **Interface:** I²C-compatible (up to 400kHz)  
- **Output Current:** 25mA per I/O (sink/source)  
- **Package:** 24-pin SSOP (Shrink Small Outline Package)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The MAX7324AEG+ is an I²C-controlled GPIO expander that provides 8 configurable I/O ports.  
- It is designed for low-voltage operation (1.71V to 5.5V), making it suitable for mixed-voltage systems.  
- The device includes internal pull-up resistors and supports interrupt output for monitoring input changes.  

### **Features:**  
- **8 Programmable I/O Pins:** Each can be independently set as an input or output.  
- **I²C Interface:** Supports standard (100kHz) and fast (400kHz) modes.  
- **Low Voltage Operation:** Works from 1.71V to 5.5V, enabling compatibility with various logic levels.  
- **High Drive Strength:** 25mA sink/source per I/O pin.  
- **Interrupt Output:** Alerts the host controller of input changes.  
- **Internal Pull-Up Resistors:** Simplifies external circuitry.  
- **Small Footprint:** 24-pin SSOP package for space-constrained designs.  

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

Application Scenarios & Design Considerations

I²C Port Expander with Eight Push-Pull Outputs and Eight Inputs

Alternative Part Number

  • PCA9555PW --: 16-bit I2C I/O expander with interrupt, functionally similar to the MAX7324 and widely available in TSSOP.
  • TCA9555PWR --: Pin-compatible 16-bit I2C I/O expander with interrupt output, direct drop-in style alternative in TSSOP package.
  • PCF8575TS --: 16-bit I2C I/O expander offering comparable port expansion functionality, suitable when interrupt support is not critical.
