DATASHEET
High ESD Protected, +125°C, 40Mbps, 3.3V, Full
Fail-Safe, RS-485/RS-422 Transceivers
ISL3179E, ISL3180E
Intersil’s ISL3179E and ISL3180E are high ESD Protected (see
Table 2), 3.3V powered, single transceivers that meet both the
RS-485 and RS-422 standards for balanced communication.
Each device has low bus currents (+220µA/-150µA), so it
presents a “1/5 unit load” to the RS-485 bus. This allows up to
160 transceivers on the network without violating the RS-485
specification’s 32 unit load maximum, and 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 terminated but undriven.
The ISL3180E is configured for full duplex applications. The
ISL3179E half duplex version multiplexes the Rx inputs and Tx
outputs to allow a transceiver with an output disable function
in 8 Ld packages.
Hot plug circuitry ensures that the Tx and Rx outputs remain in
a high impedance state while the power supply stabilizes.
Applications
• Motor controller/position encoder systems
• Factory automation
• Field bus networks
• Security networks
• Building environmental control systems
• Industrial/process control networks

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. Intersil 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). Intersil 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), please see device information page for ISL3179E, ISL3180E. For more information on MSL please see techbrief
TB363.

Pin Descriptions
PIN FUNCTION
RO Receiver output: If A-B -50mV, RO is high; If A-B -200mV, RO is low; RO = High if A and B are unconnected (floating) or shorted, or connected
to a terminated bus that is undriven.
RE Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. If the Rx enable function isn’t required,
connect RE directly to GND.
DE Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high, and they are high impedance when DE is low. If the Tx
enable function isn’t required, connect DE to VCC through a 1kΩ or greater resistor.
DI 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.
GND Ground connection. This is also the potential of the DFN’s exposed metal pad.
A/Y ±16.5kV IEC61000 ESD protected RS-485/RS-422 level, noninverting receiver input and noninverting driver output. Pin is an input (A) if
DE = 0; pin is an output (Y) if DE = 1. ISL3179E only.
B/Z ±16.5kV IEC61000 ESD protected RS-485/RS-422 level, inverting receiver input and inverting driver output. Pin is an input (B) if DE = 0;
pin is an output (Z) if DE = 1. ISL3179E only.
A ±12kV HBM ESD protected RS-485/RS-422 level, noninverting receiver input. ISL3180E only.
B ±12kV HBM ESD protected RS-485/RS-422 level, inverting receiver input. ISL3180E only.
Y ±12kV HBM ESD protected RS-485/RS-422 level, noninverting driver output. ISL3180E only.
Z ±12kV HBM ESD protected RS-485/RS-422 level, inverting driver output. ISL3180E only.
VCC System power supply input (3.0V to 3.6V).
NC No internal connection.
EP The exposed metal pad on the bottom of the DFN; connect to GND.
