8-bit Serial/parallel Register With Sign Extend

The 74F322 is an 8-bit Shift register with provision for either serial or parallel loading and with 3-State parallel outputs plus a bi-state serial output. Parallel data inputs and outputs are multiplexed to minimize pin count. State changes are initiated by the rising edge of the Clock Four synchronous modes of operation are possible: hold (store), shift right with serial entry, shift right with sign extend, and parallel load. An asynchronous Master Reset (MR) input overrides clocked operation and clears the Registers The 74F322 contains eight D-type edge triggered Flip-Flops and the interstage gating required to perform right shift and the intrastage gating necessary for hold and synchronous parallel load operations. A Low signal on RE enables shifting or parallel loading, while a High signal enables the hold mode. A High signal on S/P enables shift right, while a Low signal disables the 3-State output Buffers and enables parallel loading. In the shift right mode a High signal on SE enables serial entry from either D0 or D1, as determined by the S input. A Low signal on SE enables shift right, but Q7 reloads its contents, thus performing the sign extend function. A High signal on OE disables the 3-State output Buffers regardless of the other control inputs. In this condition the shifting and loading operations CAN still be performed. By NXP Semiconductors
