The 'LS323 is an 8-bit universal shift storage register with TRI-STATE outputs Its function is similar to the 'LS299 with the exception of Synchronous Reset Parallel load inputs and flip-flop outputs are multiplexed to minimize pin count Separate inputs and outputs are provided for flipflops Q0 and Q7 to allow easy cascading Four operation modes are possible hold (store) shift left shift right and parallel load All modes are activated on the LOW-to-HIGH transition of the Clock
