stresses in excess of the absolute maximum ratings can permanently damage the device. functional operation is not implied at these or any other conditions in excess of conditions represented in the operational sections of this data sheet. exposure to t he maximum ratings for the extended periods may adversely a ect device reliability. although esd protection circuitrry has been designed into the the fx-424, proper precautions should be taken when handling and mounting. vi employs a human body model and a charged-device model (cdm) for esd susceptibility testing and design protection evaluation. esd thresholds are dependent on the circuit parameters used to de ne the model. although no industry wide standard has been adopted for the cdm, a standard hbm of resistance=1.5kohms and capacitance = 100pf is widely used and therefore can be used for comparison purposes the fx-500 is capable of meeting the following quali cation tests reliability absolute maximum ratings table 2. absolute maximum ratings parameter symbol ratings unit power supply v dd 7v storage temperature t str -55 to 125 0c table 3. environmental compliance parameter conditions mechanical shock mil-std-883, m2002/test a mechanical vibration mil-std-883, m2007/testa lead solderability mil-std-883, m2003 gross and fine leak mil-std-883, m1014 handling precautions table 4. predicted esd r$atings model minimum conditions human body model 1000 v mil-std 883, method 3015 charged device model 1000 v jedec, jesd22-c101 rev: 14aug2009 vectron international ? 267 lowell road, hudson, nh 03051 ? tel: 1-88-vectron-1 ? http://www.vectron.com 3 of 7
