Description and Introduction

3-V to 5.5-V Multichannel RS-232 Line Driver/Receiver With +/-15-kV IEC ESD Protection 28-SSOP 0 to 70 The TRS3243ECDBRG4 is a 3-V to 5.5-V multichannel RS-232 line driver/receiver manufactured by Texas Instruments (TI)/Burr-Brown (BB).  

### **Specifications:**  
- **Supply Voltage Range:** 3 V to 5.5 V  
- **Data Rate:** Up to 1 Mbps  
- **Number of Drivers/Receivers:** 3 drivers, 5 receivers  
- **ESD Protection:** ±15 kV (Human Body Model)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SSOP (DB)  

### **Descriptions:**  
The TRS3243ECDBRG4 is designed for RS-232 communication in battery-powered, portable, and low-power applications. It integrates charge-pump circuitry to generate RS-232 voltage levels from a single 3-V to 5.5-V supply.  

### **Features:**  
- Meets EIA/TIA-232-F standards  
- Low power consumption  
- Auto-powerdown feature for power savings  
- Interoperable with 3.3-V or 5-V logic  
- Enhanced ESD protection on serial-port pins  
- Pin-compatible with industry-standard RS-232 transceivers  

This device is commonly used in industrial, telecom, and computing applications requiring robust RS-232 communication.

Application Scenarios & Design Considerations

3-V to 5.5-V Multichannel RS-232 Line Driver/Receiver With +/-15-kV IEC ESD Protection 28-SSOP 0 to 70

Alternative Part Number

  • MAX3243ECDB --: Pin-compatible RS-232 transceiver with ESD protection, same SSOP-28 footprint and 3.3V operation, widely used as a direct TI TRS3243 replacement.
  • SP3243ECA-L --: 3.3V RS-232 transceiver with auto-powerdown and ESD protection in SSOP-28, functionally equivalent to the TRS3243E family.
  • ICL3243ECAZ --: 3.3V RS-232 transceiver with ESD protection and auto-powerdown, same pinout and package options, suitable drop-in alternative.
