description
These devices contain two independent J-K positive-edge-triggered flip-flops. A low level at the preset (PRE resets the outputs regardless of the levels of the other inputs. When PRE (high), data at the J and K setup-time requirements are transferred to the outputs on the positive-going edge of the clock (CLK) 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 affecting the levels at the outputs. These versatile flip-flops can perform as toggle flip-flops by grounding K perform as D-type flip-flops if J and K together.
