Description and Introduction

2-Wire-Interfaced, 2.5V to 5.5V, 20-Port or 28-Port I/O Expander The MAX7300AAX+ is a serial-interfaced peripheral manufactured by Maxim Integrated. It provides general-purpose parallel I/O expansion for I²C-bus and SPI™-compatible interfaces.  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Interface:** I²C/SPI-compatible  
- **Number of I/O Pins:** 20  
- **Operating Voltage:** 2.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 36-pin SSOP  

### **Descriptions:**  
The MAX7300AAX+ is a versatile I/O expander that allows microcontrollers to control multiple digital inputs and outputs via a serial interface. It supports both I²C and SPI communication protocols, making it flexible for various embedded applications.  

### **Features:**  
- **20 configurable I/O pins** (can be set as inputs or outputs)  
- **Low standby current** (1µA typical)  
- **Schmitt-trigger inputs** for noise immunity  
- **Programmable reset state** for outputs  
- **400kHz I²C-compatible interface**  
- **10MHz SPI-compatible interface**  
- **Industrial temperature range** (-40°C to +85°C)  
- **Small 36-pin SSOP package** for space-constrained designs  

This device is commonly used in applications requiring additional I/O expansion, such as industrial controls, consumer electronics, and embedded systems.
