LVDS DS90C032 Heavy Ion Test

July, 1998

Test Results Summary

Additional heavy ion tests were run on the National Semiconductor DS90C032 LVDS receiver.  No latchups were observed during these test runs.

 

Run Name:    BNL0797

Part #:           DS90C032

Package:       SOIC

 

Run #    File Name     Bias(V)    LET    Fluence     Latch
  74      LVDS1B1       5.5       74.7     5E7         No
  75      LVDS2B1       5.5       74.7     1E8         No 
  76      LVDS3B1       5.5       74.7     1E8         No

100      LVDS2G2       5.5       82.6     2E7         No
101      LVDS3G1       5.5       82.6     2E7         No

 

The amount of runs was limited by available beam time.  A future test will irradiate these parts at higher fluences and LET's.
