Product Details

The MAX13430E–MAX13433E 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–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 limited, 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.
