° W ave Form ° Appli cation Circuitč1Ď: AE2501B Figure 1.Typical application circuit Note: 1. When the VIH>2V,the external resistor must add to Pin1 & Pin8 to limit i nput current.The range of resist ance should ca lculate with the following formula(the unit is KΩ) : R1,2MINĢ5.8 ×VinĒ8.7 R1,2MAX Ģ17.2 ×VinĒ25.8 2. IN A and INB can’t be high level at the same time,this state is forbid for this chip.
