Description and Introduction

Single 5V RS232/RS485 Multiprotocol Transceiver The LTC1334IG is a product from Linear Technology (now part of Analog Devices). Below are its specifications, descriptions, and features based on available factual information:

### **Specifications:**
- **Manufacturer:** LINEAR (Linear Technology)
- **Part Number:** LTC1334IG
- **Type:** RS232 Transceiver
- **Operating Voltage:** 3.3V or 5V
- **Data Rate:** Up to 250kbps
- **Number of Drivers/Receivers:** 3 Drivers, 5 Receivers
- **Package:** 28-Lead SSOP
- **Operating Temperature Range:** -40°C to +85°C
- **ESD Protection:** ±15kV (Human Body Model)
- **Supply Current (Shutdown Mode):** <1µA
- **Supply Current (Active Mode):** Typically 5mA

### **Descriptions:**
The LTC1334IG is a low-power, 3.3V/5V RS232 transceiver designed for serial communication applications. It integrates charge-pump circuitry to generate RS232 voltage levels from a single power supply. The device includes three drivers and five receivers, making it suitable for multi-channel communication systems.

### **Features:**
- **Single 3.3V or 5V Supply Operation**
- **Low Power Consumption (5mA typical)**
- **Shutdown Mode (<1µA)**
- **250kbps Data Rate**
- **±15kV ESD Protection on RS232 Pins**
- **Three RS232 Drivers and Five Receivers**
- **On-Chip Charge Pump for RS232 Voltage Levels**
- **28-Lead SSOP Package**
- **Wide Operating Temperature Range (-40°C to +85°C)**

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application notes, refer to the official datasheet from Analog Devices (formerly Linear Technology).

Application Scenarios & Design Considerations

Single 5V RS232/RS485 Multiprotocol Transceiver

Alternative Part Number

  • MAX3140CAI+ --: Quad RS-232/RS-485 transceiver in a similar SSOP package with comparable multi-protocol functionality, widely used as a Linear Technology cross-reference.
  • SP334CT-L --: Multi-protocol RS-232/RS-485 transceiver offering similar channel count and interface flexibility, suitable as a functional substitute.
  • ADM3312EARUZ --: Multi-channel RS-232 transceiver with integrated charge pump, pin-function compatible for many LTC1334 applications and readily available.
  • MAX3140CAI --: Quad RS-232/RS-485 transceiver in a 28-pin SSOP, functionally similar to the LTC1334IG with comparable multi-protocol interface capability.
  • SP334CT --: Multiprotocol serial transceiver supporting RS-232 and RS-485 modes, a common cross-reference for the LTC1334 family in industrial interfaces.
  • ADM3311EARS --: Multi-channel RS-232 transceiver with integrated charge pump, suitable as a functional substitute where full LTC1334 multiprotocol features are not strictly required.
