These arrays' seven NPN Darlington connected transistors are ideal for driving lamps, relays, or printer hammers in a wide range of industrial and consumer applications. Their high breakdown voltage and internal suppression diodes ensure that they are free of problems associated with inductive loads. Peak inrush currents of up to 500 mA allow them to power incandescent lamps. The MC1413, B, with a 2.7 k series input resistor, is ideal for systems that use 5.0 V TTL or CMOS logic.
