CD40174BC • CD40175BC Hex D-Type Flip-Flop • Quad D-Type Flip-Flop October 1987 Revised July 1999 CD40174BC • CD40175BC Hex D-Type Flip-Flop • Quad D-Type Flip-Flop General Description The CD40174BC consists of six positive-edge triggered Dtype flip-flops; the true outputs from each flip-flop are externally available. The CD40175BC consists of four positiveedge triggered D-type flip-flops; both the true and complement outputs from each flip-flop are externally available. All flip-flops are controlled by a common clock and a common clear. Information at the D inputs meeting the set-up time requirements is transferred to the Q outputs on the positive-going edge of the clock pulse. The clearing operation, enabled by a negative pulse at Clear input, clears all Q outputs to logical [ ... ]
