Dual Negative-Edge-Triggered Master-Slave

J-K Flip-Flops with Clear and Complementary Outputs

General Description

This device contains two independent negative-edge-trig-

gered J-K flip-flops with complementary outputs. The J and

K data is processed by the flip-flops on the falling edge of

the clock pulse. The clock triggering occurs at a voltage

level and is not directly related to the transition time of the

negative going edge of the clock pulse. The data on the J

and K inputs is allowed to change while the clock is HIGH

or LOW without affecting the outputs as long as setup and

hold times are not violated. A low logic level on the clear

input will reset the outputs regardless of the levels of the

other inputs.

established.

Toggle = Each output changes to the complement of its previous level on

each falling edge of the clock pulse.
