Notes:

1. Index area: a notch or a pin one identification mark shall be located

adjacent to pin one. The manufacturer's identification shall not be

used as pin one identification mark.

2. The minimum limit for dimension "b2" may be .023 (.58mm) for leads

number 1, 12, 13 and 24 only.

3. Dimension "Q" shall be measured from the seating plane to the base

plane.

4. This dimension allows for off-center lid, meniscus and glass overrun.

5. The basic pin spacing is .100 (2.54mm) between centerlines. Each

pin centerline shall be located within ±.010 (.25mm) of its exact

longitudinal position relative to pins 1 and 24.

6. Applies to all four corners (leads number 1, 12, 13, and 24).

7. "eA" shall be measured at the center of the lead bends or at the

centerline of the leads when "a" is 90¡.

8. All leads – Increase maximum limit by .003 (.08mm) measured at the

center of the flat, when lead finish applied.

9. Twenty-two spaces.
