Description
The ST485A is a low power, high speed
transceiver for RS-485 and RS-422
communications. The device contains one driver
and one receiver in half duplex configuration. The
ST485A draws 3mA (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 receiver
input has a fail-safe feature that guarantees a
logic high output if both inputs are open circuit.
The ST485A is designed for bi-directional data
communications or multipoint bus transmission
lines.
