Darlington Transistor Arrays, STMicroelectronics


Darlington transistor power drivers are high-voltage, high-current switch arrays containing multiple open-collector Darlington pairs and integral suppression diodes for inductive loads. The high current rating of each output is 500 mA or higher. The inputs are pinned opposite the outputs in the IC package to simplify the application board layout. The interface is standard logic level for TTL or CMOS.
