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 5 Volts and
ground respectively.
Testing was started at 5.0 V (Positive) or 0 V(Negative), and the DUT was
biased for 0.5 seconds.
If neither the PUT current supply nor the device current supply reached the
predefined limit (DUT=0 mA , Icc=100 mA), then the voltage was increased
by 0.1 Volts and the pin was tested again.
This procedure was recommended by the JEDEC JC-40.2 CMOS Logic
standardization committee.
Notes:
1. DUT: Device Under Test.
2. PUT: Pin Under Test.
