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 EIA485
Standard. Features include threestate outputs, thermal shutdown,
and output current limiting in both directions. These devices also
comply with EIA422A, 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 16pin plastic DIP and 20pin wide
body surface mount packages.
Meets EIA485 Standard for Party Line Operation
Meets EIA422A 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 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 μA96172/4
Interchangeable with MC3487 and AM26LS31 for EIA422A
Applications
w These devices are available in Pbfree package(s). Specifications herein
apply to both standard and Pbfree devices. Please see our website at
www.onsemi.com for specific Pbfree orderable part numbers, or contact
your local ON Semiconductor sales office or representative.
