SNJ55LBC176FK General Description

These transceivers are suitable for ANSI Standard TIA/EIA−485 (RS-485) and ISO 8482 applications to the extent that they are specified in the operating conditions and characteristics section of this data sheet. Certain limits contained in TIA/EIA−485−A and ISO 8482:1987 (E) are not met or cannot be tested over the entire military temperature range.

The SN55LBC176 is characterized for operation from –55°C to 125°C. The SN65LBC176 is characterized for operation from –40°C to 85°C, and the SN65LBC176Q is characterized for operation from –40°C to 125°C. The SN75LBC176 is characterized for operation from 0°C to 70°C.
