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).

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
