SN65LBC173A, SN75LBC173A QUADRUPLE RSĆ485 DIFFERENTIAL LINE RECEIVERS SLLS456B − NOVEMBER 2000 − REVISED APRIL 2005 D Designed for TIA/EIA-485, TIA/EIA-422, and ISO 8482 Applications D Signaling Rate† Exceeding 50 Mbps D Fail-Safe in Bus Short-Circuit, Open-Circuit, and Idle-Bus Conditions D ESD Protection on Bus Inputs Exceeds 6 kV D Common-Mode Bus Input Range –7 V to 12 V D Propagation Delay Times <16 ns D Low Standby Power Consumption <20 µA D Pin-Compatible Upgrade for AM26LS32, DS96F173, LTC488, and SN75173 description The SN65LBC173A and SN75LBC173A are quadruple differential line receivers with 3-state outputs, designed for TIA/EIA-485 (RS-485), TIA/EIA-422 (RS-422), and ISO 8482 (Euro RS-485) applications. These devices are optimized for balanced multipoint bus communication at data rates up to and exceeding 50 million bits per second. The transmission media may be twisted-pair cables, printed-circuit board traces, or backplanes. The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media and the noise coupling to the environment.
