description
The
SN55LBC176,
SN65LBC176,
SN65LBC176Q, and SN75LBC176 differential
bus transceivers are monolithic, integrated
circuits designed for bidirectional data communi-
cation on multipoint bus-transmission lines. They
are designed for balanced transmission lines and
meet ANSI Standard TIA/EIA−485−A (RS-485)
and ISO 8482:1987(E).
