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 ?0? and Q s (CD40175BC only) to logical ?1?.
All inputs are protected from static discharge by diode
clamps to VDD and VSS.
