NOTES:

1. DATUMS -L-, -M-, AND -N- ARE DETERMINED

WHERE TOP OF LEAD SHOLDERS EXITS

PLASTIC BODY AT MOLD PARTING LINE.

2. DIMENSION G1, TRUE POSITION TO BE

MEASURED AT DATUM -T-, SEATING PLANE.

3. DIMENSION R AND U DO NOT INCLUDE MOLD

FLASH. ALLOWABLE MOLD FLASH IS 0.010

(0.25) PER SIDE.

4. DIMENSIONING AND TOLERANCING PER ANSI

Y14.5M, 1982.

5. CONTROLLING DIMENSION: INCH.

6. THE PACKAGE TOP MAY BE SMALLER THAN

THE PACKAGE BOTTOM BY UP TO 0.012

(0.300). DIMENSIONS R AND U ARE DETERMINED

AT THE OUTERMOST EXTREMES OF THE

PLASTIC BODY EXCLUSIVE OF THE MOLD

FLASH, TIE BAR BURRS, GATE BURRS AND

INTERLEAD FLASH, BUT INCLUDING ANY

MISMATCH BETWEEN THE TOP AND BOTTOM

OF THE PLASTIC BODY.

7. DIMINSION H DOES NOT INCLUDE DAMBAR

PROTRUSION OR INTRUSION. THE DAMBAR

PROTUSION(S) SHALL NOT CAUSE THE H

DIMINSION TO BE GREATER THAN 0.037

(0.940146). THE DAMBAR INTRUSION(S) SHALL

NOT CAUSE THE H DIMINISION TO SMALLER

THAN 0.025 (0.635).
