54LS109 DM54LS109A DM74LS109A Dual Positive-Edge-Triggered J-K Flip-Flops
with Preset Clear and Complementary Outputs
June 1989
54LS109 DM54LS109A DM74LS109A
Dual Positive-Edge-Triggered J-K Flip-Flops
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 regardless of the
logic levels of the other inputs
