Dual-In-Line Plastic Packages (PDIP)

NOTES:

1. Controlling Dimensions: INCH. In case of conflict between English and

Metric dimensions, the inch dimensions control.

2. Dimensioning and tolerancing per ANSI Y14.5M-1982.

3. Symbols are defined in the “MO Series Symbol List” in Section 2.2 of

Publication No. 95.

4. Dimensions A, A1 and L are measured with the package seated in

JEDEC seating plane gauge GS-3.

5. D, D1, and E1 dimensions do not include mold flash or protrusions.

Mold flash or protrusions shall not exceed 0.010 inch (0.25mm).

6. E and are measured with the leads constrained to be perpendic-

ular to datum .

7. e

B

and e

C

are measured at the lead tips with the leads unconstrained.

e

C

must be zero or greater.

8. B1 maximum dimensions do not include dambar protrusions. Dambar

protrusions shall not exceed 0.010 inch (0.25mm).

9. N is the maximum number of terminal positions.

10. Corner leads (1, N, N/2 and N/2 + 1) for E8.3, E16.3, E18.3, E28.3,

E42.6 will have a B1 dimension of 0.030 - 0.045 inch (0.76 - 1.14mm).
