April 1997 ML4644* 4 Port AUI Multiplexer GENERAL DESCRIPTION The ML4644 AUI Multiplexer contains all the necessary drivers/receivers and control logic to implement a 4 port MAU when used in conjuction with a transceiver chip which has a standard 802.3 AUI interface. Several ML4644s can be cascaded together to implement an 8 or 12 port MAU or standalone device. Logic within the ML4644 detects collisions resulting from multiple DTEs transmitting simultaneously. In addition, collision signals received from a transceiver attached at the MAU port are propagated to all of the DTE ports. Jabbering DTEs are prevented from loading down the network by an internal jabber timer which disables babbling ports. FEATURES s IEEE 802.
