Description and Introduction

+5V/Adjustable Step-Up Current-Mode DC-DC Converters The MAX732EWE is a peripheral interface IC manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
MAXIM  

### **Part Number:**  
MAX732EWE  

### **Description:**  
The MAX732EWE is an I²C-compatible serial-interfaced peripheral that provides 8 bits of parallel input/output (I/O) expansion. It is designed to simplify microcontroller-based systems by adding extra I/O ports via the I²C serial interface.  

### **Key Features:**  
- **I²C-Compatible Serial Interface:** Supports standard (100kHz) and fast (400kHz) modes.  
- **8-Bit Parallel I/O Port:** Configurable as inputs or outputs.  
- **Interrupt Output:** Alerts the microcontroller of input state changes.  
- **5V Operation:** Compatible with 5V systems.  
- **Low Standby Current:** Reduces power consumption.  
- **Schmitt-Trigger Inputs:** Improves noise immunity.  
- **Open-Drain Outputs:** For flexible output configurations.  
- **Small Package:** Available in a 16-pin wide SOIC (WE) package.  

### **Applications:**  
- Microcontroller I/O expansion  
- Keypad interfaces  
- LED control  
- General-purpose input/output extension  

### **Package:**  
16-pin Wide SOIC (WE)
