CD40174BM CD40174BC Hex D Flip-Flop
CD40175BM CD40175BC Quad D Flip-Flop
General Description
The CD40174B consists of six positive-edge triggered
D-type flip-flops the true outputs from each flip-flop are ex-
ternally available The CD40175B consists of four positive-
edge triggered D-type flip-flops both the true and comple-
ment outputs from each flip-flop are externally available
All flip-flops are controlled by a common clock and a com-
mon 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 opera-
tion enabled by a negative pulse at Clear input clears all Q
outputs to logical ‘‘0’’ and Qs (CD40175B only) to logical ‘‘1’’
All inputs are protected from static discharge by diode
clamps to VDD and VSS
