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.
