Darlington devices are high-voltage, high-current switch arrays containing multiple open-collector Darlington pairs or multiple
Darlington transistors with common emitters, and integral suppression diodes for inductive loads. The nominal current rating of each output is 500 mA for the 7- and 8-output devices and up to 1.5 A for quad-output devices. The inputs are pinned opposite the outputs to simplify the application board layout. These devices interface
standard logic families.
