56F8146 Package and Pin-Out Information
ALL DIMENSIONS ARE IN MILLIMETERS.
INTERPRET DIMENSIONS AND TOLERANCES PER
ASME Y14.5M, 1994.
DATUMS B, C AND D TO BE DETERMINED AT DATUM
H.
THE TOP PACKAGE BODY SIZE MAY BE SMALLER
THAN THE BOTTOM PACKAGE SIZE BY A MAXIMUM
OF 0.1 mm.
DIMENSIONS D1 AND E1 DO NOT INCLUDE MOLD
PROTRUSIONS. THE MAXIMUM ALLOWABLE
PROTRUSION IS 0.25 mm PER SIDE. D1 AND E1 ARE
MAXIMUM BODY SIZE DIMENSIONS INCLUDING MOLD
MISMATCH.
DIMENSION b DOES NOT INCLUDE DAMBAR
PROTRUSION. PROTRUSIONS SHALL NOT CAUSE
THE LEAD WIDTH TO EXCEED 0.35. MINIMUM SPACE
BETWEEN PROTRUSION AND AN ADJACENT LEAD
SHALL BE 0.07 mm.
