Description and Introduction

+5V-Powered, Multichannel RS-232 Drivers/Receivers The MAX242EWN is a part manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX242EWN  
- **Package:** 28-pin Wide PDIP (Plastic Dual In-line Package)  
- **Operating Temperature Range:** -40°C to +85°C (Extended Industrial)  
- **Supply Voltage:** Typically operates at ±5V  
- **Interface Type:** RS-232 Transceiver  

### **Descriptions:**
- The MAX242EWN is a high-performance RS-232 transceiver designed for serial communication applications.  
- It integrates charge-pump circuitry to generate RS-232 voltage levels from a single +5V supply.  
- Suitable for industrial environments due to its extended temperature range.  

### **Features:**
- **Single +5V Supply Operation:** Eliminates the need for ±12V supplies.  
- **Onboard Charge Pump:** Generates RS-232 compliant ±10V output levels.  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **ESD Protection:** Up to ±15kV (Human Body Model) on driver outputs and receiver inputs.  
- **Compliance:** Meets EIA/TIA-232 and V.28/V.24 standards.  
- **Two Drivers and Two Receivers:** Supports full-duplex communication.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Alternative Part Number

  • ADM202EARNZ --: Pin-compatible dual RS-232 transceiver from a different series; widely available and a common drop-in replacement for MAX242 in 5V systems.
  • ST202ECDR --: Dual RS-232 driver/receiver functionally equivalent to MAX242, offered in SOIC package with similar electrical characteristics and lower cost.
  • ICL202ECPZ --: Industry-standard dual RS-232 transceiver with comparable charge-pump design and pinout, suitable as a second-source alternative.
  • ADM232AAN --: Pin-compatible RS-232 transceiver with similar dual-driver/receiver functionality and 5V operation, widely available as a direct substitute.
  • ST232ACN --: Equivalent 5V RS-232 driver/receiver in a DIP package with comparable data rate and drive capability, suitable drop-in replacement.
  • ICL232CPE --: Classic dual RS-232 transmitter/receiver with similar electrical characteristics and DIP footprint, usable as an alternative with minor external component checks.
