... All devices have a 1/8-unit-load receiver input imped- ance that allows up to 256 transceivers on the bus. The MAX3082/MAX3085/MAX3088 are intended for half- duplex communications, while the MAX3080/MAX3081/ MAX3083/MAX3084/MAX3086/MAX3087 are intended for full-duplex communications. The MAX3089 is selec- table between half-duplex and full-duplex operation ...

... Reflections section). The MAX3083/MAX3084/MAX3085 offer higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The MAX3086/ MAX3087/MAX3088’s driver slew rates are not limited, making transmit speeds up to 10Mbps possible. The MAX3089’s slew rate is selectable between 115kbps, 500kbps, and 10Mbps by driving a selector pin with a three-state driver ...
