4-78. The 1820-0788 (Figure 4-34) consists of six positive-edge-triggered
mation at the D inputs is transferred to the
pulse. Clock triggering occurs at a particular voltage level and is not directly related to the
transition time of the positive-going pulse. When the clock input is a t either the high or low level,
the D input has no effect on the output.

complementary outputs from each flip-flop.
