Dual D-Type Positive-Edge-Triggered Flip-Flops with Preset and Clear
These devices contain two independent D-type positive-edge-triggered flip-flops. A low level at the
preset or clear inputs sets or resets the outputs regardless of the levels of the other inputs. When
preset and clear are inactive (high), data at the D input meeting the setup time requirements are
transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at
a voltage level and is not directly related to the rise time of the clock pulse. Following the hold time
interval, data at the D input may be changed without affecting the levels at the outputs.
