2018 HS-26C32EH Total Dose Test 2. Results 2.1 Attributes Data Testing of the HS-26C32EH at LDR showed no rejected devices after irradiation, screening to the SMD limits. The SMD specifies that the part will meet all pre-irradiation limits post-irradiation because the pre-irradiation limits and post-irradiation limits are the same. No bias sensitivity was noted. Table 1. HS-26C32EH Total Dose Test Attributes Data 2.2 Variables Data The plots in Figures
3 through
21 show data at all downpoints. Most of the plots show the individual total dose response of each of the four channels. Note that error bars are not supplied for this data because the distributions were tight enough to render this unnecessary. Dose Rate Bias Sample Size Downpoint Bin

2018 HS-26C32EH Total Dose Test Figure 4. HS-26C32EH enable HIGH and LOW input voltage as a function of biased (Figure 2) and unbiased (grounded) LDR irradiation to 100krad(Si). The sample size for each of the LDR cells was 16. The SMD limit is 3.85V maximum (enable HIGH voltage) and 1.65V minimum (enable LOW input voltage). Figure 5. HS-26C32EH tristate output leakage, output at VDD, each channel, as a function of biased (Figure 2) and unbiased (grounded) LDR irradiation to 100krad(Si). The sample size for each of the LDR cells was 16. The SMD limits are -5000nA (-5?A) to +5000nA (+5?A). 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5
