Irradiation Circuit

NOTES:

10. VDD = 5.0V

±0.5V

11. R2 = 3.3k

Ω, R3 = 47kΩ

12. Pins Tied to GND: 1-18, 20, 23, 39

Pins Tied to VCC: 22, 31, 33, 40

Pins With Loads: 24-29, 30, 32, 34-38

Pins Brought Out: 19 (Clock), 21 (Reset)

13. Clock and reset should be brought out separately so they can be toggled before irradiation.

14. Group E Sample Size is 2 Die/Wafer.
