±16.5kV ESD, Large Output Swing, 5V, Full
Fail-Safe, 1/8 Unit Load, RS-485/RS-422
Transceivers
ISL3150E, ISL3152E, ISL3153E,
ISL3155E, ISL3156E, ISL3158E
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 ±16.5kV ESD
strikes without latch-up.
Transmitters in this family deliver exceptional differential
output voltages (2.4V min), into the RS-485 required
54Ω 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 28mA @
V
= 1V (to ease the design of optocoupled isolated
OL
interfaces).
Half duplex (Rx inputs and Tx outputs multiplexed
together) and full duplex pinouts are available. See
Table 1 on page 2 for key features and configurations by
device number.
