General Description

The MAX13430E–MAX13433E are full- and half-duplex

RS-485 transceivers that feature an adjustable low-volt-

age logic interface for operation in multivoltage systems.

This allows direct interfacing to low-voltage ASIC/FPGAs

without extra components. The MAX13430E–MAX13433E

from +3V to +5V. The low-voltage logic interface operates

The MAX13430E/MAX13432E feature reduced slew-

rate drivers that minimize EMI and reduce reflections

caused by improperly terminated cables, allowing

error-free data transmission up to 500kbps. The

MAX13431E/MAX13433E driver slew rates are not limit-

ed, enabling data transmission up to 16Mbps. The

MAX13430E/MAX13431E are intended for half-duplex

communications, and the MAX13432E/MAX13433E are

intended for full-duplex communications.

The MAX13430E/MAX13431E are available in 10-pin

MAX13433E are available in 14-pin TDFN and 14-pin

SO packages.
