    5.6. Latch-Up Test Results Test Description: Latch-Up testing was performed at room ambient using an IMCS-4600 system which applies a stepped voltage to one pin per device with all other pins open except Vdd and Vss which were biased to 5Volts and ground respectively. Testing was started at 5.0V (Positive) or 0V (Negative), and the DUT was biased for 0.5 seconds.
