NOTES:

1. DUE TO SPACE LIMITATION, CASE 777-02

SHALL BE REPRESENTED BY A GENERAL

(SMALLER) CASE OUTLINE DRAWING

RATHER THAN SHOWING ALL 44 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 0.25 (0.010) 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 .012 (.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 .037

(.940). THE DAMBAR INTRUSION(S) SHALL

NOT CAUSE THE H DIMENSION TO BE

SMALLER THAN .025 (.635).

9. 777-01 IS OBSOLETE, NEW STANDARD 777-02.
