MAX13430E–MAX13433E
RS-485 Transceivers with Low-Voltage
Logic Interface
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 VCC voltage 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.
