The output associated with the specific input will be held low if the voltage on the input pin is less than
1.25V. If the voltage is above 1.25V the output will not sink current and will be pulled up by the required
pull up resistor. The value of the resistors is not critical in most cases but must be set low enough to pull
the output to a high state. A common value used is 10k W . If a NMI output is connected to a pushbutton
input an additional pull-up resistor can be used (to improve speed of transitions) but is not required.
During a power-up, any detected IN pin levels above V TP by the comparator are disabled from generating
an inactive (high) interrupt until at least 1 supply on the V IN inputs rises above 1.5 volts. All NMI outputs
will be held active (low) until at least one V IN reaches 1.5 volts at which point the NMI outputs will be
based on the value of the associated IN input.
