HD74HC175
HD74HC175 is Quad. D-typ Flip-Flops (with Clear) manufactured by Hitachi Semiconductor.
Description
Information at the D inputs of the HD74HC175 is transferred to the Q and Q outputs on the positive going edge of the clock pulse. Both true and pliment outputs from each flip-flop are externally available. All four flip flops are controlled by a mon clock and a mon clear. Clearing is acplished by a negative pulse at the clear input. All four Q outputs are cleared to a logic low level and all four Q outputs to a logic high level.
