Ⅰ、General Description:
The AME4620 analog switches feature low ON resistance, single-pole, double-throw (SPDT) with
wide operating single power supply voltage range, from 1.8V to 5.5V.
AME4620 has 1Ω max ON resistance when +5V power supply is used. These products also have fast
switching speeds, tON = tOFF = 50nS max.
AME4620 is available in SC-70-6.
Ⅱ、Product Information:
Ⅲ、Failures In Time Calculation:
Use HTOL test information mentioned in sectionⅣ, FIT (Failures In Time) can be calculated as below:
FIT = ( x 2 (ν ,
CL )
× 10 9 ) /( 2 × S × H × AF ) = ( 4 .61 × 10 9 ) /( 2 × 77 × 1000 × 280 .59 )
=106.69 (pieces per 109 hours) @ 40℃ with 90% Confidence Level.
Where AF is acceleration factor setting activation energy to 1.0eV as zero failure.
