Description and Introduction

8-Channel Analog Multiplexer with Cascadable Serial Interface The LTC1391IGN is a low-power, single-supply RS232 transceiver manufactured by Linear Technology (now part of Analog Devices). Below are the specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Linear Technology (LT)  
- **Part Number:** LTC1391IGN  
- **Type:** RS232 Transceiver  
- **Supply Voltage (VCC):** 3.3V or 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SSOP (Narrow)  
- **Data Rate:** Up to 120kbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **ESD Protection:** ±10kV (Human Body Model)  
- **Shutdown Current:** <1µA (Typical)  

### **Descriptions:**
The LTC1391IGN is a single RS232 transceiver designed for low-power applications. It operates from a single 3.3V or 5V supply, making it suitable for battery-powered and portable devices. The device includes an onboard charge pump to generate RS232-compatible voltage levels (±5V). It features automatic power-down to minimize current consumption when not in use.

### **Features:**
- Single 3.3V or 5V Supply Operation  
- Low Power Consumption (Shutdown Mode: <1µA)  
- Onboard Charge Pump for RS232 Voltage Levels (±5V)  
- 1 Driver and 1 Receiver  
- ESD Protection: ±10kV (HBM)  
- Operates Up to 120kbps Data Rate  
- 16-Lead SSOP Package  
- Suitable for Battery-Powered and Portable Applications
