9 2A The SN55LBC172 is a monolithic quadruple
differential line driver with 3-state outputs. This
device is designed to meet the requirements of the
Electronics Industry Association (EIA) standard
RS-485. The SN55LBC172 is optimized for
balanced multipoint bus transmission at data
rates up to and exceeding 10 million bits per
second. The driver features wide positive and
negative common-mode output voltage ranges, …
