This IC can be used whether or not a pull-up resistor is included in the logic circuit. Note 2. The logic circuit preferably should not have a pull-down resistor. However in the case it has, the load resistor RL must be much less than the pull-down resistor. (refer to the above application circuit) ! Mitsubishi Electric Corporation puts the maximum effort into making semiconductor products better and more reliable, but there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury,fire or property damage.Remember to give due consideration to safety when making your circuit design,in order to prevent fires from spreading,redundancy,malfunction or other mishap.
