description
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 preset and clear are inactive
(high), dataattheJandKinputsmeetingthesetup
time requirements are transferred to the outputs
on the positive-going edge of the clock pulse.
Clocktriggeringoccursatavoltagelevelandisnot
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
tying J high. They also can perform as D-type
flip-flops by tying the J and K inputs together.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
