Updated the Ordering Information table to include only lead-free parts and changed the pin-
package for EMOD to EDIP; updated the Absolute Maximum Ratings section to include the
storage temperature range and lead and soldering temperatures for EDIP and PowerCap
packages; added Note 11 to the ICC parameter in the DC Electrical Characteristics tables
(for 5.0V and 3.3V) and the Notes section; replaced the package outline drawings with the
