Setting of Output Load Resistance (M51953B/M51954)
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.
2. Please set output load resistance (pull-up resistance) RL so that the output current (output inflow current IL) at L
level may become 4 mA or less. Moreover, please never exceed absolute maximum rating (6 mA).
