DESCRIPTION

· The ST3485E is a 3.3V powered, ±15kV ESD protected RS-485/RS-422 transceiver.
· It operates without a charge pump and is interoperable with 5V logic.
· Features a half-duplex configuration with one driver and one receiver.
· Ensures a data rate of up to 12Mbps and supports up to 64 transceivers on the bus.

FEATURES

· ESD protection: ±15kV human body model, ±8kV IEC 1000-4-2 contact discharge.
· Operates from a single 3.3V supply, with a 1µA low current shutdown mode.
· Common mode input voltage range from -7V to 12V.
· Driver overload protection with current limiting and thermal shutdown.
· Guaranteed high receiver output state for floating inputs.

APPLICATIONS

· Suitable for industrial and commercial RS-485/RS-422 communication systems.
· Ideal for applications requiring robust ESD protection and high-speed data transmission.
· Used in environments where multiple transceivers are needed on a single bus.
