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.

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.

I have searched for "Code Warrior" on Google, but I can't find what I need. Does anyone know where I can find an integrated development environment (CodeWarrior) for arm?
I also searched on http://www.gnu.org, but some of them cannot be downloaded, and some development environments are commercial. Please advise! Thank you!...
