Philips 74F323
The 74F323 is an 8-bit universal shift/storage register with 3-State outputs. Its function is similar to the 74F299 with the exception of synchronous Reset. The 74F323 contains eight edge-triggered D-type flip-flops and the interstage logic necessary to perform synchronous reset, shift left, shift right, parallel load, and hold operations.| Part No. | 74F323 |

FEATURES
● Common parallel I/O for reduced pin count● Additional serial inputs and outputs for expansion
● Four operating modes: Shift left, shift right, load, and store
● 3-State outputs for bus-oriented applications
DESCRIPTION
Parallel load inputs and flip-flop outputs are multiplexed to minimize pin counts. Separate serial inputs and outputs are provided for flip-flops Q0 and Q7 to allow easy serial cascading. Four modes of operation are possible: Hold (store), shift left, shift right, and parallel load. The type of operation is determined by S0 and S1, as shown in the Function Table. All flip-flop outputs are brought out through 3-State buffers to separate I/O pins that also serve as data inputs in the parallel load mode. Q0 and Q7 are also brought out on other pins for expansion in serial shifting of longer words. A Low signal on SR overrides the Select and inputs and allows the flip-flops to be reset by the next rising edge of clock. All other state changes are initiated by the rising edge of the clock.
