DATE REVISION CHANGE
June 28, 2016 FN2867.10 Converted to new datasheet template.
Updated 14 Ld PDIP “Pin Configuration” on page 1 by adding “1” or “2” to pins that have same name.
Updated “Thermal Information” on page 3 by removing Maximum Lead Temperature and Adding T
JC
values with corresponding note.
Updated “Ordering Information” table on page 2 by removing obsoleted parts, adding Tape and Reel
option column, adding MSL note and numbering notes accordingly.
Updated POD M8.15 to most current version. POD changes are as follows:
Changed in Typical Recommended Land Pattern the following:
2.41(0.095) to 2.20(0.087)
0.76 (0.030) to 0.60(0.023)
0.200 to 5.20(0.205)
Updated to new POD format by removing table and moving dimensions onto drawing and adding land
pattern
