Description and Introduction

+5V-Powered, Multichannel RS-232 Drivers/Receivers The MAX233AEWP is a dual RS-232 driver/receiver manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Interface Type:** RS-232  
- **Number of Drivers/Receivers:** 2 Drivers, 2 Receivers  
- **Data Rate:** Up to 120kbps  
- **Supply Voltage:** Single +5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin Wide SOIC (SO)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Built-in Charge Pump:** Requires no external capacitors  
- **Compliance:** Meets EIA/TIA-232 and V.28/V.24 standards  

### **Descriptions & Features:**  
- **Dual RS-232 Transceiver:** Integrates two drivers and two receivers.  
- **Single +5V Supply:** Eliminates the need for ±12V supplies.  
- **On-Board Charge Pump:** Generates RS-232 voltage levels (±10V) internally.

Application Scenarios & Design Considerations

+5V-Powered, Multichannel RS-232 Drivers/Receivers

Alternative Part Number

  • ADM233LJNZ --: Pin-compatible dual RS-232 transceiver with integrated charge pump, functionally equivalent to the MAX233A in a 20-pin DIP/SOIC package.
  • ST233ECDR --: Dual RS-232 driver/receiver with on-chip charge pump, similar supply and data-rate specs, suitable drop-in replacement in most designs.
  • ICL233ECPZ --: Equivalent dual RS-232 transceiver with internal charge pump capacitors, matching pinout and electrical characteristics for the MAX233A.
  • SP233ACT --: Drop-in dual RS-232 transceiver with internal charge pump, widely used as a MAX233 substitute in industrial designs.
