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.
Both devices are available in 16−pin plastic PDIP and 20−pin wide
body surface mount packages.
Features
• Meets EIA−485 Standard for Party Line Operation
• Meets EIA−422−A and CCITT Recommendations V.11 and X.27
• Operating Ambient Temperature: −40°C to +85°C
• High Impedance Outputs
• Common Mode Output Voltage Range: −7.0 to 12 V
• Positive and Negative Current Limiting
• Transmission Rates in Excess of 10 MBPS
• Thermal Shutdown at 150°C Junction Temperature, (± 20°C)
• Single 5.0 V Supply
• Pin Compatible with TI SN75172/4 and NS mA96172/4
• Interchangeable with MC3487 and AM26LS31 for EIA−422−A
Applications
• Pb−Free Packages are Available*

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
1. Devices should not be operated at these limits. The “Recommended Operating
Conditions” table provides for actual device operation.
