Description and Introduction

3-V to 5.5-V Multichannel RS-232 Line Driver/Receiver The MAX3238CPW is a 3.0V to 5.5V-powered RS-232 transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 3.0V to 5.5V  
- **Data Rate:** Up to 250kbps  
- **Number of Drivers/Receivers:** 3 drivers, 5 receivers  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** TSSOP-28  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Low Power Consumption:** 1µA (typical shutdown current)  
- **Compliance:** Meets EIA/TIA-232 and V.28/V.24 standards  

### **Descriptions:**
The MAX3238CPW is a low-power, multi-channel RS-232 transceiver designed for serial communication applications. It integrates charge-pump circuitry to generate RS-232 voltage levels from a single 3V to 5.5V supply, eliminating the need for external power supplies. The device includes three drivers and five receivers, making it suitable for systems requiring multiple RS-232 ports.

### **Features:**
- **Auto-Shutdown/Enable:** Automatically enters low-power mode when no valid signal is detected.  
- **Enhanced ESD Protection:** ±15kV on transmitter outputs and receiver inputs.  
- **Small Footprint:** 28-pin TSSOP package for space-constrained applications.  
- **Wide Supply Voltage Range:** Supports 3V to 5.5V operation.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Compatible with 3V/5V Logic:** Works with both 3V and 5V microcontrollers.  

The MAX3238CPW is commonly used in industrial control, networking, and embedded systems requiring reliable RS-232 communication.
