8-bit Shift Register
The 74LS323 is an 8-Bit Universal Shift/Storage Register with 3-state outputs. Its function is similar to the 74LS299 with the exception of Synchronous Reset. Parallel load inputs and flip-flop outputs are multiplexed to minimize pin count.
SN74LS164 8-Bit Shift Register
The SN74LS164 is a high-speed 8-Bit Serial-In Parallel-Out Shift Register. The input Serial data is given through a 2-Input AND gate synchronous with the LOW to HIGH transition of the clock.
