.. MICROCIRCUIT DATA SHEET MN54ABT646-X REV 0B0 Original Creation Date: 08/25/95 Last Update Date: 10/05/98 Last Major Revision Date: 03/19/97 OCTAL TRANSCEIVERS AND REGISTERS WITH 3-STATE OUTPUTS General Description The ABT646 consists of bus tranceiver circuits wit TRI-STATE, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to a high logic level. Control OE and direction pins are provided to control the transceiver function. In the transceiver mode, data present at the high...
