This device contains two independent D-type negative-edge-triggered flip-flops. All inputs include Schmitt-triggers, allowing for slow or noisy input signals. A low level at the preset (PRE) input sets the output high. A low level at the clear (CLR) input resets the output low. Preset and clear functions are asynchronous and not dependent on the levels of the other inputs. When PRE and CLR are inactive (high), data at the data (D) input meeting the setup time requirements is transferred to the outputs (Q, Q) on the negative-going edge of the clock (CLK) pulse. Following the hold-time interval, data at the data (D) input can be changed without affecting the levels at the outputs (Q, Q).
