Pad requirement to accommodate two package types is larger than for one package type.
All dimensioning and tolerancing conform to ANSI Y14.5M-1982. Dimensions in mm.
Datums A--B and --D-- to be determined from the center two leads.
Based on the surface mount Design and Land Pattern Standard in IPC-SM-782 rev. A,
