DM74ALS109A
Dual J-K Positive-Edge-Triggered Flip-Flop
with Preset and Clear
General Description
The DM74ALS109A is a dual edge-triggered flip-flop. Each
flip-flop has individual J, K, clock, clear and preset inputs,
and also complementary Q and Q outputs.
Information at input J or K is transferred to the Q output on
the positive going edge of the clock pulse. Clock triggering
occurs at a voltage level of the clock pulse and is not
directly related to the transition time of the positive going
pulse. When the clock input is at either the HIGH or LOW
level, the J, K 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-K design allows operation as a D flip-flop by tying the
J and K inputs together.

Note 1:
This condition is nonstable; it will not persist when present and
clear inputs return to their inactive (HIGH) level. The output levels in this
condition are not guaranteed to meet the V
