Notes
Rev. A | Page 32 of 56
For a NAND tree test to work, all outputs (INT, RSTMAIN,
RSTSTBY, and PWM) must remain high during the test.
When generating test waveforms, allow for a typical
propagation delay of 500 ns through the NAND tree.
If any of the inputs shown in Figure 56 are unused, they
should not be connected direct to ground, but via a resistor
such as 10 k. This allows the automatic test equipment
(ATE) to drive every input high so that the NAND tree test
can be properly carried out.

Figure 57. NAND Tree Test Taking Inputs High in Turn
In the event of an input being nonfunctional (stuck high or low)
or two inputs shorted together, the output pattern is different.
Some examples are given in Figure 59 through Figure 61.
Figure 59 shows the effect of one input being stuck low. The
output pattern is normal until the stuck input is reached.
Because that input is permanently low, neither it nor any inputs
further up the tree can have any effect on the output.
