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.
