MAX9100/MAX9101
+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
Figure 3 shows an application that converts 3V logic
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
Figure 4 shows an application that converts 1V logic
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.
