Description and Introduction

Triple Differential Bus Transceiver The SN75ALS171DWR is a quad differential line driver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** Quad Differential Line Driver  
- **Supply Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Output Current:** ±60mA (max)  
- **Propagation Delay:** 10ns (typical)  
- **Package:** SOIC-16 (DWR)  

### **Descriptions:**  
- Designed for balanced digital data transmission.  
- Compatible with RS-422 and RS-485 standards.  
- Features four independent differential line drivers.  
- Provides high-speed data transmission with low power consumption.  

### **Features:**  
- **High-Speed Operation:** Supports data rates up to 20Mbps.  
- **Low Power Consumption:** Typically 80mW per driver.  
- **Wide Supply Voltage Range:** 4.5V to 5.5V.

This device is commonly used in industrial, telecommunications, and networking applications requiring reliable differential signaling.

Application Scenarios & Design Considerations

Triple Differential Bus Transceiver

Alternative Part Number

  • DS26LS31CM --: Quad differential line driver in the same RS-422/RS-485 family class; pin-compatible function and widely available as a direct functional substitute.
  • AM26LS31CDR --: Quad differential line driver with equivalent signaling characteristics; commonly used as a drop-in replacement for SN75ALS171 in RS-422 applications.
  • MC3487DR --: Quad differential line driver offering similar drive capability and supply requirements; suitable alternative when the original is unavailable.
