Controlling Dimensions: MILLIMETER. In case of conflict between English and Metric dimensions, the metric dimensions control. 2. Dimensions A, A1 and L are measured with the package seated in JEDEC seating plane gauge GS-3. 3. D and E1 dimensions do not include mold flash or protrusions. 4. eA is measured with the leads constrained to be perpendicular to base plane. 5. N is the maximum number of terminal positions. 13 MILLIMETERS e 0.100 BSC 2.54 BSC - eA 0.600 BSC 15.24 BSC 4 L 0.119 N α - 3.0 28 o 0 - 2 28 15 o o 0 5 15 o Rev. 1 4/95
