Product Overview: SN75LBC173AN

The SN75LBC173AN is a high-performance quadruple differential line receiver designed by Texas Instruments to meet the stringent requirements of the TIA/EIA-485 standard. This device is specifically crafted to operate in environments that demand robust noise immunity and high data integrity.

Key Features

  • Interface Type: RS-485/RS-422
  • Supply Voltage Range: 4.75V to 5.25V
  • Signaling Rate: Up to 10 Mbps
  • Number of Receivers: 4
  • Temperature Range: -40°C to 85°C
  • Package: PDIP (Plastic Dual In-line Package) 16-pin
  • Fail-Safe Protection: Ensures a high output state when inputs are left open


The SN75LBC173AN is adept for use in a wide array of applications that require reliable data transmission over long distances or in electrically noisy environments. These applications include industrial control systems, building automation, network equipment, and data communication systems.

Performance and Durability

Designed for optimal performance, the SN75LBC173AN boasts a differential input threshold range that ensures signal integrity, even with voltage level shifts. Its robust fail-safe feature guarantees a known output state in the absence of an input signal, which is critical for maintaining system reliability. Additionally, the integrated thermal shutdown protects the device from damage due to excessive power dissipation.

Quality and Reliability

As with all Texas Instruments products, the SN75LBC173AN is manufactured to the highest quality standards. It undergoes rigorous testing to ensure it meets the industrial temperature grade specifications. This commitment to quality and reliability makes the SN75LBC173AN a trusted component for critical communication systems.

Easy Integration

The industry-standard PDIP 16-pin package allows for easy integration into existing designs, and the device's compatibility with multiple receiver standards ensures its versatility across different platforms. With its plug-and-play nature, the SN75LBC173AN simplifies the design process, enabling engineers to focus on creating innovative solutions without worrying about communication integrity.
