The MM54C175 MM74C175 consists of four positive-edge triggered D type flip-flops implemented with monolithic CMOS technology Both are true and complemented outputs from each flip-flop are externally available All four flipflops 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 positivegoing edge of the clock pulse The clearing operation enabled by a negative pulse at Clear input clears all four Q outputs to logical ``0'' and Q's to logical ``1''
