The M63820FP/KP is transistor-array of high active level eight units type which can do direct drive of 3 voltage microcomputer series. A resistor of 1.05k is connected between the input pin. A clamp diode for inductive load transient suppression is connected for the output pin (collector) and COM pin (pin11). All emitters of the output transistor are connected to GND (pin10). The outputs are capable of driving 500mA and are rated for operation with output voltage up to 50V.
