DWG. # CA3240AE -40 to 85 8 Ld PDIP E8.3 CA3240AEZ (See Note) -40 to 85 8 Ld PDIP (Pb-free) E8.3 CA3240E -40 to 85 8 Ld PDIP E8.3 CA3240EZ (See Note) -40 to 85 8 Ld PDIP (Pb-free) E8.3 Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications. NOTE: Intersil Pb-free products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

CA3240, CA3240A FN1050 Rev 6.00 Page 2 of 15 March 4, 2005 Absolute Maximum Ratings Thermal Information Operating Conditions Thermal Resistance (Typical, Note 2) JA (oC/W) *Pb-free PDIPs can be used for through hole wave solder process - ing only. They are not intended for use in Reflow solder proces sing applications. CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress o nly rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTES: 1. Short circuit may be applied to ground or to either supply. Temperatures and/or supply voltages must be limited to keep dissipation within max- imum rating. 2. JA is measured with the component mounted on an evaluation PC board in free air.
