The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E,

and MAX1487E are low-power transceivers for RS-485 and

RS-422 communications in harsh environments. Each driver

output and receiver input is protected against ±15kV electrostatic

discharge (ESD) shocks, without latchup. These parts

contain one driver and one receiver. The MAX483E,

MAX487E, MAX488E, and MAX489E feature reduced slewrate

drivers that minimize EMI and reduce reflections caused

by improperly terminated cables, thus allowing error-free

data transmission up to 250kbps. The driver slew rates of the

MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E

are not limited, allowing them to transmit up to 2.5Mbps.
