Post Radiation Electrical Specifications VDIFF = 3V, TA = +25°C, unless otherwise noted. Boldface limits apply over a total

ionizing dose of 300krad(Si) with exposure at a high dose rate of 50 to 300krad(Si)/s; or over a total ionizing dose of 50krad(Si) with exposure a low dose

rate of <10mrad(Si)/s.

NOTE:

8. Compliance to datasheet limits is assured by one or more methods: production test, characterization, and/or design.

Post Radiation Characteristics This data is a typical mean test data post total dose radiation exposure at both a low dose rate (LDR)

of <10mrad(Si)/s to 100krad(Si) and at a high dose rate (HDR) of 50 to 300rad(Si)/s to 300krad(Si). This data is intended to show typical parameter

shifts due to low dose rate radiation. These are not limits nor are they guaranteed.
