DM54ALS109A/DM74ALS109A Dual J-K Positive-Edge-Triggered Flip-Flops with Preset and Clear
General Description
The DM54ALS109A is a dual edge-triggered flip-flop. Each flip-flop has individual J,
K.
clock, clear and preset inputs, and also complementarya
anda
outputs.Information at input J or
R
is transferred to thea
output onthe positive going edge of the clock pulse. Clock triggering occurs at a voltage level of the clock pulse and is not direct-ly related to the transition time of the positive going pulse.
When the clock input is at either the high or low level, the J,
R
input signal has no effect.Asynchronous preset and clear inputs will set or clear Q output respectively upon the application of low level signal.
The
J-R
design allows operation as a 0 flip-flop by tying the J andR
inputs together.Connection Diagram
