DM54LS107A DM74LS107A Dual Negative-Edge-Triggered Master-Slave J-K Flip-Flops with Clear and Complementary Outputs June 1989 DM54LS107A DM74LS107A Dual Negative-EdgeTriggered Master-Slave J-K Flip-Flops with Clear and Complementary Outputs General Description This device contains two independent negative-edge-triggered 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 may 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 [ ... ]
