The MAX13431E are full- and half-duplex RS-485 transceivers that feature an adjustable low-voltage logic interface for operation in multivoltage systems. This allows direct interfacing to low-voltage ASIC/FPGAs without extra components. The MAX13431E RS-485 transceivers operate with a V_CC voltage supply from +3V to +5V. The low-voltage logic interface operates with a voltage supply from +1.62V to V_CC.

The MAX13431E driver slew rates are not limited, enabling data transmission up to 16Mbps. The MAX13431E are intended for half-duplex communications.

The MAX13431E are available in 10-pin µMAX® and 10-pin TDFN packages.
