... 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 ...
