NOTES:
Rev. 1 6/99
1. These package dimensions are within allowable dimensions
of JEDEC MO-153-AET, Issue E.
2. Dimensioning and tolerancing per ANSI Y14.5M-1982.
3. Dimension “D” does not include mold flash, protrusions or
gate burrs. Mold flash, protrusion and gate burrs shall not
exceed 0.15mm (0.006 inch) per side.
4. Dimension “E1” does not include interlead flash or protru-
sions. Interlead flash and protrusions shall not exceed
0.15mm (0.006 inch) per side.
5. The chamfer on the body is optional. If it is not present, a vi-
sual index feature must be located within the crosshatched
area.
6. “L” is the length of terminal for soldering to a substrate.
7. “N” is the number of terminal positions.
8. Terminal numbers are shown for reference only.
9. Dimension “b” does not include dambar protrusion. Allow-
able dambar protrusion shall be 0.08mm (0.003 inch) total
in excess of “b” dimension at maximum material condition.
Minimum space between protrusion and adjacent lead is
0.07mm (0.0027 inch).
10. Controlling dimension: MILLIMETER. Converted inch di-
mensions are not necessarily exact. (Angles in degrees)
11. Dimensions “P” and “P1” are thermal and/or electrical en-
hanced variations. Values shown are maximum size of ex-
posed pad within lead count and body size.
