The Motorola MC75172B/174B Quad Line drivers are differential high  
speed drivers designed to comply with the EIA–485 Standard. Features  
include three–state outputs, thermal shutdown, and output current limiting in  
both directions. These devices also comply with EIA–422–A, and CCITT  
Recommendations V.11 and X.27.  
The MC75172B/174B are optimized for balanced multipoint bus  
transmission at rates in excess of 10 MBPS. The outputs feature wide  
common mode voltage range, making them suitable for party line  
applications in noisy environments. The current limit and thermal shutdown  
features protect the devices from line fault conditions. These devices offer  
optimum performance when used with the MC75173 and MC75175 line  
receivers.
