- **Common-Mode Voltage Range:** -7V to +12V  

### **Descriptions:**
The LTC1385CSW is a low-power, high-speed RS-485/RS-422 transceiver designed for robust communication in noisy environments. It integrates a single driver and receiver with enhanced ESD protection, making it suitable for industrial and telecom applications.  

### **Features:**
- **Low Power Consumption:** Operates at 1.2mA typical quiescent current.  
- **High-Speed Operation:** Supports data rates up to 10Mbps.  
- **Enhanced ESD Protection:** ±15kV HBM protection on bus pins.  
- **Wide Common-Mode Range:** -7V to +12V for noise immunity.  
- **Fail-Safe Receiver:** Ensures logic-high output when inputs are open or shorted.  
- **Half-Duplex Operation:** Suitable for bidirectional communication.  
- **Thermal Shutdown Protection:** Prevents damage during fault conditions.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application notes, refer to the official datasheet.

Application Scenarios & Design Considerations

3.3V Low Power EIA/TIA-562 Transceiver

Alternative Part Number

  • MAX3221ECAE+ --: Single-channel RS-232 transceiver with similar 3V/5V operation and low-power shutdown, functionally comparable to the LTC1385 in many serial interface designs.
  • SP3223ECA-L --: RS-232 transceiver with auto-online plus shutdown, offering comparable driver/receiver count and supply range for drop-in style replacement.
  • ADM3202ARNZ --: Low-power RS-232 transceiver with 3V/5V supply and similar pinout family, widely used as an alternative for LT RS-232 interface parts.
  • SP3223ECY-L --: RS-232 transceiver offering similar driver/receiver count and supply range, suitable drop-in functional replacement for serial interface designs.
