LATCHUP TEST CONFIGURATION

Figure 43 shows the latchup test. VDD holds at +5.5 VDC, and

VSS holds at ground. The device test is at 125°C. Each type of

I/O alternately receives a positive and then negative 150 mA

pulse of 500 ms duration. The current is monitored after the

pulse for latchup condition. To prevent burnout, the supply

current is limited to 400 mA.

The UT1750AR has latchup immunity in excess of +150 mA

for 500 ms.
