Description
The ST485 is al low power transceiver for RS-485
and RS-422 communication. Each part contains
one driver and one receiver.
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 placed the driver
outputs into a high-impedance state.
The ST485 is designed for bi-directional data
communications on multipoint bus transmission
line (half-duplex applciations).
The ST485 is available in three temperature
range: commercial (0°C to 70°C), industrial (-
40°C to 85°C) and automotive (-55°C to 125°C)
