Aug 31, 2017 В±16.5kV ESD, Large Output Swing, 5V, Full Fail-Safe, 1/8 Unit Load,
RS-485/RS-422 Transceivers
The ISL315xE are IEC61000 ESD protected, 5V
powered transceivers that meet the RS-485 and
RS-422 standards for balanced communication. Driver
outputs and receiver inputs are protected against
В±16.5kV ESD strikes without latch-up.
Transmitters in this family deliver exceptional
differential output voltages (2.4V min), into the
RS-485 required 54О© load, for better noise immunity,
or to allow up to eight 120Ω terminations in “star”
topologies.
These devices have very low bus currents so they
present a true “1/8 unit load” to the RS-485 bus. This
allows up to 256 transceivers on the network without
using repeaters.
Receiver (Rx) inputs feature a “Full Fail-Safe” design,
which ensures a logic high Rx output if Rx inputs are
floating, shorted, or on a terminated but undriven
bus. Rx outputs feature high drive levels -typically …
