TECHNICAL DATA
ILX3485
Low-Power, Slew-Rate-Limited RS-485/RS-422
Transceivers
General Description
The ILX3485 is low-power transceivers for RS-485-3.3 and
RS- 422-3.3 communication. IC contains one driver and one
receiver. The driver slew rates of the ILX3485 is not limited,
allowing them to transmit up to 2.5Mbps.
These transceivers draw between 120µA and 500µA of supply
current when unloaded or fully loaded with disabled drivers. All
parts operate from a single 3.3V 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.
