8-Bit Universal Shift/Storage Register
with Synchronous Reset and Common I/O Pins
General Description
The ’LS323isan 8-bit universal shift/storage register with
TRI-STATEÉ outputs.Its functionis similartothe ’LS299
withthe exceptionof Synchronous Reset. Parallel loadin-
puts and flip-flop outputsare multiplexedto minimizepin
count. Separate inputs and outputsare providedforflip-
flopsQ0 andQ7to allow easy cascading. Four operation
modesare possible: hold (store), shiftleft, shift right,and
parallel load.All modesare activatedonthe LOW-to-HIGH
transitionofthe Clock.
Features CommonI/Ofor reducedpin count Four operation modes: shiftleft, shift right, parallel load
and store Separate continuous inputs and outputs fromQ0 and allow easy cascading Fully synchronous reset TRI-STATE outputsforbus oriented applications
