SLLS897E – MARCH 2008 – REVISED JUNE 2015 ISO1176 Isolated RS-485 Profibus Transceiver
1 Features 3 Description The ISO1176 device is an isolated differential line
transceiver designed for use in PROFIBUS
applications. The device is ideal for long transmission
lines because the ground loop is broken to provide for
operation with a much larger common-mode voltage
range. The symmetrical isolation barrier of each
device is tested to provide 2500 VRMS of isolation per
UL between the line transceiver and the logic level
interface. 1 Meets or Exceeds the Requirements of
EN 50170 and TIA/EIA-485-A
Signaling Rates up to 40 Mbps
Differential Output Exceeds 2.1 V (54-Ω Load)
Low Bus Capacitance – 10 pF (Maximum)
Up to 160 Transceivers on a Bus
50 kV/Ојs Typical Transient Immunity
Fail-Safe Receiver for Bus Open, Short, Idle …
