...Dual Rank 8-Bit TRI-STATE Shift RegisterGeneral DescriptionThese circuits are TRI-STATE, edge-triggered, 8-bit I/O reg-isters in parallel with 8-bit serial shift registers which are... ...load from I/O pins to register ‘‘A’’, parallel transfer downfrom register ‘‘A’’ to serial shift register ‘‘B’’, parallel transferup from shift register ‘‘B’’ to register ‘‘A’’, serial shift of regis-ter ‘‘B’’, or exchange data between register ‘‘A’’ and shift... ...positive transition of the clock, the control lines which deter-mine the mode or operation are completely independent ofthe logic level applied to the clock. Designed for bus-orient-ed systems, these circuits have their TRI-STATE inputs and...
