    NOTES:
    1. Dimensioning and tolerancing conform to ASME Y14.5-1994.
    2. N is the number of terminals.
    3. Nd and Ne refer to the number of terminals on each D and E.
    4. All dimensions are in millimeters. Angles are in degrees.
    5. Dimension b applies to the metallized terminal and is measured
    between 0.15mm and 0.30mm from the terminal tip.
    6. The configuration of the pin #1 identifier is optional, but must be
    located within the zone indicated. The pin #1 identifier may be
    either a mold or mark feature.
    7. Dimensions D2 and E2 are for the exposed pads which provide
    improved electrical and thermal performance.
    8. Nominal dimensions are provided to assist with PCB Land Pattern
    Design efforts, see Intersil Technical Brief TB389.
    9. Features and dimensions A2, A3, D1, E1, P &
    θ are present when
    Anvil singulation method is used and not present for saw
    singulation.
    10. Compliant to JEDEC MO-220VHHC Issue I except for the "b"
    dimension.
