CD40174BCN Datasheet PDF - Fairchild

General Description

●The CD40174BC consists of six positive-edge triggered D type flip-flops; the true outputs from each flip-flop are externally available. The CD40175BC 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 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 Qs (CD40175BC only) to logical “1”. All inputs are protected from static discharge by diode clamps to VDDand VSS.
