SN54/74LS299 8-BIT SHIFT/STORAGE REGISTER WITH 3-STATE OUTPUTS The SN54 / 74LS299 is an 8-Bit Universal Shift / Storage Register with 3-state outputs. Four modes of operation are possible: hold (store), shift left, shift right and load data. The parallel load inputs and flip-flop outputs are multiplexed to reduce the total number of package pins. Separate ou.
