Description and Introduction

Differential Bus Transceiver The SN75ALS176B is a differential bus transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** Differential Bus Transceiver  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 20 Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Bus Pins ESD Protection:** ±15 kV (Human Body Model)  
- **Package Options:** DIP (8-pin), SOIC (8-pin)  
- **Compliance:** Meets or exceeds ANSI TIA/EIA-422-B and ITU V.11 standards  

### **Descriptions and Features:**  
- Designed for bidirectional data communication on multipoint bus transmission lines.  
- Features differential outputs and inputs for noise immunity.  
- Includes thermal shutdown protection to prevent damage from excessive power dissipation.  
- High input impedance minimizes loading effects on the bus.  
- Suitable for RS-422 and RS-485 applications.  
- Driver is enabled when DE (Driver Enable) is high, and receiver is enabled when RE (Receiver Enable) is low.  
- Low-power consumption in standby mode.  

This device is commonly used in industrial control, networking, and telecommunications applications.

Application Scenarios & Design Considerations

Differential Bus Transceiver

Alternative Part Number

  • MAX485ESA+ --: Industry-standard RS-485/RS-422 transceiver with the same half-duplex differential bus function and 5V supply; widely available and pin-compatible in function, making it a strong drop-in alternative.
  • SN75176BP --: Classic RS-485 differential bus transceiver from the same vendor with equivalent driver/receiver functionality and 5V operation; a well-known, cost-effective substitute.
  • ADM485ARZ --: Low-power RS-485 transceiver with comparable data rate and 5V supply, offering similar electrical performance and a different series naming for easy distinction.
