Octal Serial/Parallel Register with Sign Extend
General Description
The ’F322isan 8-bit shift register with provisionfor either
serialor parallel loadingand with TRI-STATEÉ parallelout-
puts plusa bi-state serial output. Parallel data inputsand
parallel outputsare multiplexedto minimizepin count. State
changesare initiatedbythe rising edgeofthe clock. Four
synchronous modesof operationare possible: hold (store),
shift right with serial entry, shift right with sign extendand
parallel load.An asynchronous Master Reset (MR) input
overrides clocked operationand clearsthe register.
Features Multiplexed parallelI/O ports Separate serial input and output Sign extend function TRI-STATE outputsforbus applications
