Description and Introduction

+5V-Powered, Multichannel RS-232 Drivers/Receivers The MAX232ESE is a dual driver/receiver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX232ESE  
- **Type:** Dual Driver/Receiver  
- **Interface Type:** RS-232  
- **Number of Drivers:** 2  
- **Number of Receivers:** 2  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-SOIC (150 mil)  
- **Data Rate:** 120kbps  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Supply Current (Max):** 8mA  

### **Descriptions:**  
The MAX232ESE is a dual RS-232 transceiver designed for serial communication applications. It includes a capacitive voltage generator to provide RS-232 voltage levels from a single 5V supply. The device is commonly used in microcontroller-to-PC communication, industrial systems, and embedded applications requiring RS-232 compatibility.  

### **Features:**  
- **Single 5V Power Supply:** Eliminates the need for ±12V supplies.  
- **Onboard Charge Pump:** Generates RS-232-compliant ±7.5V outputs.  
- **Low Power Consumption:** Typically 5mA supply current.  
- **ESD Protection:** Protects against electrostatic discharge up to ±15kV.  
- **Compatible with TTL/CMOS Logic Levels:** Interfaces easily with microcontrollers.  
- **Wide Operating Temperature Range:** Suitable for industrial environments.  

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

Application Scenarios & Design Considerations

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

Alternative Part Number

  • ST232ECDR --: Pin-compatible RS-232 transceiver with dual charge pump, widely available and cost-effective drop-in replacement for MAX232ESE.
  • ICL232CPE --: Classic dual RS-232 driver/receiver with similar functionality and pinout, suitable for 5V systems requiring MAX232-equivalent performance.
  • SP232ECP --: Low-power RS-232 transceiver with integrated charge pump, functionally equivalent to MAX232ESE and commonly used as a cross-reference alternative.
  • SP232ECP-L --: Pin-compatible RS-232 transceiver with equivalent dual driver/receiver functionality and similar electrical characteristics, widely used as a MAX232 drop-in replacement.
  • ST232ECN --: Industry-standard 5V RS-232 transceiver with the same driver/receiver count and pinout, suitable for direct substitution in most MAX232ESE applications.
  • ST232EBDR --: Industry-standard dual RS-232 driver/receiver functionally equivalent to MAX232, available in SOIC package with similar electrical characteristics.
