Description and Introduction

+3V to +5.5V RS-232 Transceivers with AutoShutdown The MAX3243CAI-T is a RS-232 transceiver manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** RS-232 Transceiver  
- **Number of Drivers/Receivers:** 3 Drivers, 5 Receivers  
- **Data Rate:** Up to 250kbps  
- **Supply Voltage:** 3V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SSOP (Shrink Small Outline Package)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Low Power Consumption:** Auto-shutdown and wake-up features  

### **Descriptions:**  
The MAX3243CAI-T is a 3.3V-powered RS-232 transceiver designed for battery-powered and low-voltage applications. It integrates charge-pump circuitry to generate RS-232 voltage levels from a single 3.3V supply. The device includes three drivers and five receivers, making it suitable for applications requiring multiple RS-232 ports.  

### **Features:**  
- **Low-Voltage Operation:** Works with 3V to 5.5V supply.  
- **Auto-Shutdown:** Reduces power consumption when inactive.  
- **Enhanced ESD Protection:** ±15kV on I/O pins.  
- **Compliant with EIA/TIA-232 and V.28/V.24 Standards.**  
- **On-Chip Charge Pump:** Eliminates the need for external voltage converters.  
- **Flow-Through Pinout:** Simplifies PCB layout.  

This device is commonly used in industrial, telecom, and portable electronics requiring reliable RS-232 communication.
