Intersil Full-Failsafe Transceiver
Families
Intersil offers a wide range of full-failsafe RS-485/RS-422
transceiver families, and receiver only ICs, as shown in Table 1.
Most of the transceiver families include half and full duplex
configurations, and a variety of data rates including slew rate
limited versions for low data rate applications.
Intersil Corporation reserves the right to make changes in circuit design, software and/or specifications at any time without notice. Accordingly, the reader is

Conclusion
A Loss-of-Signal (LOS) indicator may be useful for
communication systems, but a standard RS-485 transceiver is ill
suited to detect the LOS condition. If the RS-485 network utilizes
transceivers with full-failsafe receivers, then additional circuitry
can be added to implement the LOS detector.
