HIGH SPEED TIL
SYNCHRONOUS OPERATION
The truth table defines the next state of the
flip-flop after a low-to-hlgh transition of the
clock pulse. The next state is a function of the
present state and the J and K inputs as shown
in the table.
The J and K inputs in the table refer to the basic
flip-flop J and K inputs as indicated on the
logic diagrams. These internal inputs are for
every flip-flop the result of a logic operation on
the external J and K inputs. This operation is
represented symbolically by AND gates in the
logic diagram for each flip-flop. Logic diagrams
are in accordance with MIL Standard 806B.
The L* symbol in the J and K input column is
defined as meaning that that input does not go
high at any time while the clock is low.
The H* symbol in the J and K input column is
defined as meaning that the input has been
high at some time while the clock was low.
The X symbol indicates that the condition of
that input has no effect on the next state of the
flip-flop.
The Hand L symbols refer to steady state high
and low voltage levels, respectively.
UNUSED INPUTS
The 9001, 9020 and 9022 all have active level
low synchronous inputs. When not in use they
must be grounded. All other unused inputs
including asynchronous should be tied high for
maximum operating speed. Use one of the
methods recommended on Page 3.
