2. The top package body size may be smaller
than the bottom package body size by as
much as 0.15 mm.
3. To be determined at seating plane.
4. Dimensions D1 and E1 do not include
mold protrusion. Allowable protrusion
is 0.25 mm per side. D1 and E1 are
maximum plastic body size dimensions
including mold mismatch.
5. Details of Pin 1 identifier optional, but
must be located within the zone indicated.
6. All dimensions are in millimeters.
7. Dimension b does not include Dambar
protrusion. Allowable Dambar protrusion
shall not cause the lead width to exceed
the maximum b dimension by more than
0.08 mm. Dambar cannot be located
on the lower radius or the foot. Minimum
space between protrusion and an
adjacent lead is 0.07 mm for 0.4 mm and
0.5 mm pitch packages.
8. Exact shape of each corner is optional.
9. These dimensions apply to the flat
section of the lead between 0.10 mm
and 0.25 mm from the lead tip.
10. A1 is defined as the distance from the
seating plane to the lowest point of the
package body.

HIGH-PERFORMANCE PRODUCTS
Description
Features
The SK1925 is an extremely fast, stable, and accurate
low skew 1:9 clock / signal distributor featuring a
synchronous enable, which allows the outputs to be
turned off and on without the risk of an upredictable
output pulse. It is also capable of receiving inputs of
any technology or voltage level. The D - flip-flop is
triggered on the falling edge of the clock.

HIGH-PERFORMANCE PRODUCTS
Description
Features
The SK1999 is an extremely fast, stable, and accurate
low skew 1:9 clock / signal distributor featuring a
synchronous enable, which allows the outputs to be
turned off and on without the risk of an unpredictable
output pulse. The D - flip-flop is triggered on the falling
edge of the clock.
