Description and Introduction

RS232/EIA562/RS485 Transceivers The LTC1322CSW is a specific model of integrated circuit (IC) manufactured by Linear Technology (now part of Analog Devices). Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
Linear Technology (Analog Devices)  

### **Part Number:**  
LTC1322CSW  

### **Package:**  
SOIC (Small Outline Integrated Circuit), 16-pin  

### **Category:**  
Interface IC  

### **Description:**  
The LTC1322CSW is a **RS232 Transceiver** designed for serial communication applications. It integrates charge-pump circuitry to generate RS232 voltage levels from a single power supply, eliminating the need for additional external components.  

### **Key Features:**  
1. **Single 5V Supply Operation** – Generates RS232-compliant voltage levels (±10V) without requiring dual power supplies.  
2. **Integrated Charge Pump** – Includes on-board voltage converters for RS232 signal generation.  
3. **Low Power Consumption** – Typically consumes **5mA** in shutdown mode.  
4. **High Data Rate** – Supports data rates up to **120kbps**.  
5. **ESD Protection** – Provides **±10kV** ESD protection on RS232 I/O pins.  
6. **Three Drivers and Five Receivers** – Includes multiple transmitters and receivers for versatile communication.  
7. **Shutdown Mode** – Allows power-saving operation when not in use.  
8. **Industrial Temperature Range** – Operates from **-40°C to +85°C**.  

### **Applications:**  
- Serial communication interfaces  
- Industrial control systems  
- Embedded systems  
- Point-of-sale terminals  
- Modems and networking equipment  

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