1. The HC technology has been shown to be vulnerable to total dose radiation levels as low as 3 Krads. DC parametric specification limits were exceeded after radiation exposure as low as 3 Krads and functional failures occurred at levels as low as 20 Krads. Lot by lot radiation testing is recommended.
2. The only remaining QPL supplier for this device will no longer be producing this device type in this grade. These parts are not recommended for new designs. Consult with the supplier for final shipment dates and/or availability information.
