Setting of Output Load Resistance (RNA51953B)

High level output voltage can be set without depending on the power-supply voltage because the output terminal is an

open collector type. However, please guard the following notes.

1. Please set it in value (2 V to 17 V) within the range of the power-supply voltage recommendation.

Moreover, please never impress the voltage of maximum ratings 18 V or more even momentarily either.

level may become 4 mA or less. Moreover, please never exceed absolute maximum rating (6 mA).
