NOTES

The above diagrams use a 20-lead PLCC package to show symbols for package dimensions The table below indicates

dimensions in mm that are specific to the 44-lead PLCC package

1 All dimensions and tolerances conform to ANSI Y145M-1982

2 Datum plane

located at top of mold parting line and coincident with top of lead where lead exits plastic body

3 Datums D–E and F–G to be determined where center leads exit plastic body at datum plane

4 To be determined at seating plane

5 Dimensions D1 and E1 do not include mold protrusion

6 Pin 1 identifier is located within one of the two defined zones

7 Locations to datum

and

to be determined at plane

8 These two dimensions determine maximum angle of the lead for certain socket applications If unit is intended to be

socketed it is advisable to review these dimensions with the socket supplier

9 Controlling dimension inch

10 All dimensions and tolerances include lead trim offset and lead plating finish

11 Tweezing surface planarity is defined as the furthest any lead on a side may be from the datum The datum is estab-

lished by touching the outermost lead on that side and parallel to D–E or F–G
