Dual Positive-Edge-Triggered J-K Flip-Flop with Preset/ Clear/ and Complementary Outputs
DM74LS109A Dual Positive-Edge-Triggered J-K Flip-Flop with Preset, Clear, and Complementary Outputs June 1986 Revised March 2000 DM74LS109A Dual Positive-Edge-Triggered J-K Flip-Flop with Preset, Clear, and Complementary Outputs General Description This device contains two independent positive-edge-trig- gered J-K flip-flops with complementary outputs. The J and K data is accepted by the flip-flop on the rising edge of the clock pulse. The triggering occurs at a voltage level and is not directly related to the transition time of the rising edge of the clock. The data on the J and K inputs may be changed while the clock is HIGH or LOW as long as setup and hold times are not violated. A low logic level on the preset or clear inputs will set or reset the outputs regard- less of the logic levels of the other inputs.

Connection Diagram Function Table Inputs Outputs PR CLR CLK J K QQ LH X X X H L HL X X X L H L L X X X H (Note 1) H (Note 1) HH ↑ LL L H HH ↑ H L Toggle HH ↑ LH Q Q 0 0 HH ↑ HH H L HH L X X Q Q 0 0 H = HIGH Logic Level L = LOW Logic Level X = Either LOW or HIGH Logic Level ↑ = Rising Edge of Pulse Q = The output logic level of Q before the indicated input conditions were 0 established. Toggle = Each output changes to the complement of its previous level on each active transition of the clock pulse. Note 1: This configuration is nonstable; that is, it will not persist when pre- set and/or clear inputs return to their inactive (HIGH) state. © 2000 DS006368
