Large 3V Output Swing, 16.5kV ESD, Full Fail-Safe, 1/8 Unit Load,
RS-485/RS-422 Transceivers
The ISL315xE family of 5V powered RS-485/RS-422
transceivers features high output drive and high ESD
protection. The devices withstand ±16.5kV IEC61000-4-
2 ESD strikes without latch-up. The large output voltage
of 3.1V typical into a 54Ω load provides high noise
immunity, and enables the drive of up to 8000ft long bus
segments, or eight 120Ω terminations in a star topology.
These devices possess less than 125µA bus input
currents, thus constituting a true 1/8 unit load. The high
output drive combined with the low bus input currents
allows for connecting up to 512 transceivers on the same
bus.
The receiver inputs feature a full fail-safe design that
turns the receiver outputs high when the bus inputs are
open or shorted.
The ISL315xE family includes half and full-duplex
transceivers with active-high driver-enable pins and
active-low receiver enable pins. These transceivers
support data rates of 115kbps, 1Mbps, and 20Mbps.
Their performance is characterized from -40°C to +85°C.

Notes:
1. Refer to
TB347
for details about reel specifications.
2. These Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100%
matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering
operations). Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), see the product information pages for the
ISL3150E, ISL3152E, ISL3153E, ISL3155E,
ISL3156E,
and
ISL3158E.

Function
Receiver output: If A-B
≥
-50mV, RO is high; If A-B
≤
-200mV, RO is low. RO is Fail-safe
High if A and B are unconnected (open) or shorted.
Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is
high.
Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They
are high impedance when DE is low.
Driver input. A low on DI forces output Y low and output Z high. Similarly, a high on DI forces
output Y high and output Z low.
Ground connection.
Non-inverting receiver input and non-inverting driver output. Pin is an input if DE = 0; pin is
an output if DE = 1.
Inverting receiver input and inverting driver output. Pin is an input if DE = 0; pin is an output
if DE = 1.
