Designer’s Data for “Worst Case” Conditions — The Designer’s Data Sheet permits the design of most circuits entirely from the information presented. SOA Limit
curves — representing boundaries on device characteristics — are given to facilitate “worst case” design.
Preferred devices are Motorola recommended choices for future use and best overall value.
