The MAX13430E 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 MAX13430E 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 MAX13430E 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 MAX13430E are intended for half-duplex communications.

The MAX13430E are available in 10-pin µMAX® and 10-pin TDFN packages.
