Dual J-K Negative-Edge-Triggered Flip-Flops with Preset
These devices contain two independent J-K negative-edge-triggered flip-flops. A low level at the
preset input sets the outputs regardless of the levels of the other inputs. When preset (PRE) is
inactive (high), data at the J and K inputs meeting the setup time requirements are transferred to the
outputs on the negative-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 J
and K inputs may be changed without affecting the levels at the outputs. These versatile flip-flops can
perform as toggle flip-flops by tying J and K high.
