STMicroelectronics ST485E
The ST485E is al low power transceiver for RS-485 and RS-422 communication. Each driver output and receiver input is protected against ±15KV electrostatic discharge (H.B.M.) (ESD) shocks, without latcup.

APPLICATIONS
-7V TO 12V COMMON MODE INPUT VOLTAGE RANGE DRIVER MAINTAINS HIGH IMPEDANCE IN 3-STATE OR WITH THE POWER OFF 70mV TYPICAL INPUT HYSTERESIS 30ns PROPAGATION DELAYS, 5ns SKEW OPERATE FROM A SINGLE 5V SUPPLY CURRENT LIMITING AND THERMAL SHUTDOWN FOR DRIVER OVERLOAD PROTECTION ESD PROTECTION: ±15KV (H.B.M.) ±8KV (IEC-1000-4-2 CONTACT DISCHARGE) ALLOWS UP TO 64 TRANSCEIVERS ON THE BUS DIP SOPDESCRIPTION
This transceiver draw 300µA (typ.) of supply current when unloaded or fully loaded with disabled drivers. It operates from a single 5V supply. Driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that place the driver outputs into a high-impedance state. The ST485E is designed for bi-directional data communications on multipoint bus transmission line (half-duplex applications).
