MAX9015–MAX9020
SOT23, Dual, Precision, 1.8V, Nanopower
Comparators With/Without Reference
15
Maxim Integrated
Logic-Level Translator
The open-drain comparators can be used to convert 5V
logic to 3V logic levels. The MAX9020 can be powered
by the 5V supply voltage, and the pullup resistor for the
MAX9020’s open-drain output is connected to the 3V
supply voltage. This configuration allows the full 5V
logic swing without creating overvoltage on the 3V logic
inputs. For 3V to 5V logic-level translations, connect the
3V supply voltage to V
CC
and the 5V supply voltage to
the pullup resistor.
