April 1997 ML4642 AUI Multiplexer GENERAL DESCRIPTION The ML4642 AUI Multiplexer contains all the necessary drivers/receivers and control logic to implement a 2 port MAU when used in conjuction with a transceiver chip which has a standard 802.3 AUI interface. In addition, the ML4642 is capable of operating in stand-alone mode where it interconnects two DTEs in the absence of a network MAU. Several ML4642s can be cascaded together to implement a 4 or 8 port MAU or stand-alone device. Logic within the ML4642 detects collisions resulting from multiple DTEs transmitting simultaneously. In addition, collision signals received from a transceiver attached at the MAU port are propagated to both of the DTE ports.
