RS-485 Transceivers with Low-Voltage Logic Interface
AVAILABLE
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
RS-485 transceivers operate with a VCCvoltage supply
from +3V to +5V. The low-voltage logic interface operates
with a voltage supply from +1.62V to VCC.
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
µMAX®and 10-pin TDFN packages. The MAX13432E/
MAX13433E are available in 14-pin TDFN and 14-pin
SO packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1:Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-
layer board. For detailed information on package thermal considerations, refer to /thermal-tutorial.
