4.4 TQFP48 Package
Figure 4.2. TQFP48
Note:
1. Dimensions and tolerance per ASME Y14.5M-1994
2. Control dimension: Millimeter.
3. Datum plane AB is located at bottom of lead and is coincident with the lead where the lead exists
from the plastic body at the bottom of the parting line.
4. Datums T, U and Z to be determined at datum plane AB.
5. Dimensions S and V to be determined at seating plane AC.
6. Dimensions A and B do not include mold protrusion. Allowable protrusion is 0.250 per side. Dimen-
sions A and B do include mold mismatch and are determined at datum AB.
7. Dimension D does not include dambar protrusion. Dambar protrusion shall not cause the D dimension
to exceed 0.350.
8. Minimum solder plate thickness shall be 0.0076.
9. Exact shape of each corner is optional.
