3 Description
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).
