NOTES:
1. All dimensions are in inches, unless otherwise noted.
2. BSC—Basic lead Spacing between Centers.
3. D & E do not include mold flash or protutions.
4. Formed leads shall be planar with respect to one another and within .004”
at the seating plane.
5. ND & NE represent the number of leads in the D & E directions respec-
tively.
6. D1 & E1 should be measured from the bottom of the package.
7. PLCC is pin & form compatible with MQUAD; the MQUAD package is used
in other RISController family members.
