双JK正沿触发触发器具有清零和预设 DUAL J-K POSITIVE-EDGE-TRIGGERED FLIP-FLOPS WITH CLEAR AND PRESET
These devices contain two independent J-K\ positive-edge-triggered flip-flops. A low level at the preset PRE\\\\ or clear CLR\\\\ inputs sets or resets the outputs regardless of the levels of the other inputs. When PRE\ and CLR\ are inactive high, data at the J and K\ 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 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 grounding K\ and trying J high. They also can perform as D-type flip-flops if J and K\ are tied together.
