MC75172B, MC75174B
Quad EIA−485 Line Drivers
with Three−State Outputs
The ON Semiconductor 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.
