●Variable Pull-up Resistance

The CONT Terminal pull-up resistance changes in response to the input level. When CONT is tied

“LOW” level, the

pull-up resistance is large, reducing the current consumed by the resistance. When CONT is left open circuit, the

pull-up resistance is small, which increases the input susceptibility to external noise. However, the pull-up

resistance ties the CONT Terminal

“High” level to prevent external noise from unexpectedly stopping the output.
