Description and Introduction

3.3V Low Power EIA/TIA-562 Transceiver The LTC1385ISW is a product from **Linear Technology** (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Linear Technology (LINEAR)  
- **Part Number:** LTC1385ISW  
- **Type:** RS-232 Transceiver  
- **Package:** SOIC-20 (Wide)  
- **Operating Voltage:** 3V to 5.5V  
- **Data Rate:** Up to 120kbps  
- **Number of Drivers/Receivers:** 3 Drivers, 5 Receivers  
- **Operating Temperature Range:** -40°C to +85°C  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Supply Current (Active):** 5mA (Typical)  
- **Supply Current (Shutdown):** 1µA (Typical)  

### **Descriptions:**
The LTC1385ISW is a **low-power, 3-driver/5-receiver RS-232 transceiver** designed for **3V to 5.5V systems**. It includes an **on-chip charge pump** to generate RS-232 voltage levels from a single supply, eliminating the need for external voltage converters. It is suitable for **battery-powered and portable applications** due to its low power consumption and shutdown mode.

### **Features:**
- **Single 3V to 5.5V Supply Operation**  
- **Low Power Consumption:**  
  - 5mA (Active Mode)  
  - 1µA (Shutdown Mode)  
- **On-Chip Charge Pump for RS-232 Voltage Levels**  
- **±15kV ESD Protection on RS-232 Pins**  
- **Meets EIA/TIA-232 and V.28/V.24 Standards**  
- **Flow-Through Pinout for Easy PCB Layout**  
- **Wide Operating Temperature Range (-40°C to +85°C)**  
- **Small Footprint (SOIC-20 Package)**  

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

Application Scenarios & Design Considerations
