DM74LS109A - Dual Positive-Edge-Triggered J-K Flip-Flop

General Description

This device contains two independent positive-edge-triggered 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.

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-triggered 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.
