JEDEC Variation All Dimensions in Millimeters
All dimensions and tolerancing conforms to ANSI Y14.5M-1982. 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.

SK1500
1:5 Signal Distribution
HIGH-PER.ORMANCE PRODUCTS HIGH-PER.ORMANCE PRODUCTS Description
The SK1500 is an extremely fast, stable, and accurate low skew 1:5 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. The SK1500 uses standard open emitter ECL outputs optimized for: * General purpose ECL compatible applications * Multiple destination applications (daisy chain).

SK1527
Anything to PECL Translator
HIGH-PER.ORMANCE PRODUCTS Description
The SK1527 is an extremely fast, stable, and accurate low skew 1:5 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. The SK1527 uses 50 outputs with source /sink capability, and is optimized for: * High speed clock / data lines that require translation * Point to point, double termination applications
