NOTES:
1. DUE TO SPACE LIMITATION, CASE 778-02 SHALL BE
REPRESENTED BY A GENERAL (SMALLER) CASE
OUTLINE DRAWING RATHER THAN SHOWING ALL 52
LEADS.
2. DATUMS -L-, -M-, AND -N- DETERMINED WHERE TOP OF
LEAD SHOULDER EXITS PLASTIC BODY AT MOLD
PARTING LINE.
3. DIM G1, TRUE POSITION TO BE MEASURED AT DATUM -T-,
SEATING PLANE.
4. DIM R AND U DO NOT INCLUDE MOLD FLASH.
ALLOWABLE MOLD FLASH IS 0.010 (0.250) PER SIDE.
5. DIMENSIONING AND TOLERANCING PER ANSI Y14.5M,
1982.
6. CONTROLLING DIMENSION: INCH.
7. 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 MOLD
FLASH, TIE BAR BURRS, GATE BURRS AND INTERLEAD
FLASH, BUT INCLUDING ANY MISMATCH BETWEEN THE
TOP AND BOTTOM OF THE PLASTIC BODY.
8. DIMENSION H DOES NOT INCLUDE DAMBAR
PROTRUSION OR INTRUSION. THE DAMBAR
PROTRUSION(S) SHALL NOT CAUSE THE H DIMENSION
TO BE GREATER THAN 0.037 (0.940). THE DAMBAR
INTRUSION(S) SHALL NOT CAUSE THE H DIMENSION TO
BE SMALLER THAN 0.025 (0.635).
