Figure 7. Package outline for QFN8 (1.4 x 1.2 x 0.55 mm) - 0.40 mm pitch

1. Dimension b applies to the metallized terminal and is measured between 0.10 and 0.20 mm from the

terminal tip. If the terminal has the optional radius on the other end of the terminal, dimension b should not

be measured in that radius area.

2. Applied only for terminals.

3. Bilateral coplanarity zone applies to the exposed heatsink slug as well as the terminals.

4. Dimensions and tolerancing conform to ASME Y14.5M - 1994.
