MAX485
Low-Power, Slew-Rate-Limited RS-485/RS-422
Transceivers
General Description
The
MAX485
is low-power transceivers for RS-485 and RS-
422 communication. IC contains one driver and one receiver.
The driver slew rates of the
MAX485
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 5V 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. The MAX485 is
designed for half-duplex applications.
