The 7475 is a quad Bistable Latch with LS technology ideally suited for use as temporary storage for binary information between processing units and input/output or indicator units. Information present at a data (D) input is transferred to the Q-output when the enable (C) is high and the Q-output will follow the data input as long as the enable remains high. When the enable goes low, the information is retained at the Q-output until the enable is permitted to go high.
