Setting of Output Load Resistance (M51945B/M51946B)
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.
2. Please set output load resistance (pull-up resistance) R
Others
1. Notes when IC is handled are published in our reliability handbook, and please refer it.
2. Additionally, please inquire of our company when there is an uncertain point on use.
