DESCRIPTION
The 74F109 is a dual positive edge-triggered JK-type flip-flop
featuring individual J, K
complementary outputs. Set (S
active low inputs and operate independently of the clock (CP) input.
The J and K
are edge-triggered inputs which control the state
changes of the flip-flops as described in the function table. Clock
triggering occurs at a voltage level and is not directly related to the
transition time of the positive-going pulse. The J and K
, clock, set, and reset inputs; also true and
D) and reset (RD) are asynchronous
inputs must
be stable just one setup time prior to the low-to-high transition of the
clock for predictable operation. The JK
D flip-flop by tying J and K
inputs together. Although the clock input
design allows operation as a
is level sensitive, the positive transition of the clock pulse between
the 0.8V and 2.0V levels should be equal to or less than the clock to
output delay time for reliable operation.
