+1.0V Micropower SOT23 Comparators

leads are long. Minimize signal lead lengths to reduce

stray capacitance between the input and output that

might cause instability.

Typical Application

Logic-Level Translator

3V to 5V

levels to 5V logic levels. The push-pull output MAX9100

is powered by the +5V supply voltage, and the invert-

ing input is biased to +1.5V with two resistors. This con-

figuration allows a full 5V swing at the output,

maximizing the noise margin of the receiving circuit.

1V to 3V

levels to 3V logic levels. The MAX9101 is powered by

the +1V supply voltage, and the pullup resistor for the

output is connected to the +3V supply voltage. The

inverting input is biased to +0.5V with two resistors.
