54F 74F322 Octal Serial Parallel Register with Sign Extend
General Description
The ’F322 is an 8-bit shift register with provision for either serial or parallel loading and with TRI-STATE parallel outputs plus a bi-state serial output Parallel data inputs and parallel 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 register
