These devices contain two independent J-K negative-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
and
are inactive (high), data at the J and K inputs meeting the setup-time requirements is transferred to the outputs on the negative-going edge of the clock pulse (CLK). Clock triggering occurs at a voltage level and is not directly related to the fall 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.
