TECHNICAL DATA
Low-Power, Slew-Rate-Limited RS-485/RS-422
Transceivers
ILX485
Description
The ILX485 is low-power transceivers for RS-485
and RS- 422 communication. IC contains one driver and
one receiver.
The driver slew rates of the ILX485 is not limited,
allowing them to transmit up to 10 Mbps.
These transceivers draw between 120µA and 500µA
of supply current when unloaded or fully loaded with
disabled drivers. All parts operate from a single 5V supply.
Drivers are short-circuit current limited and are protected
against excessive power dissipation by thermal shutdown
circuitry that places the driver outputs into a high-
impedance state.
The receiver input has a fail-safe feature that
guarantees a logic-high output if the input is open circuit.
The ILX485 is designed for half-duplex applications.

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
