Product Details

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.

STMicroelectronics ULN2803A Darlington pair is a is a through hole eight Darlington array in DIP package. The array consists of eight Darlington transmitters with common emitters and integral suppression diodes for inductive loads. Each Darlington features a peak load current rating of 600 mA (500 mA continuous) and can withstand at least 50 V in the OFF state.
