SLRS049G –FEBRUARY 1997–REVISED JANUARY 2015
ULN2803A Darlington Transistor Arrays
1 Features 3 Description
The ULN2803A device is a high-voltage, high-current
1
• 500-mA-Rated Collector Current
Darlington transistor array. The device consists of
(Single Output)
eight NPN Darlington pairs that feature high-voltage
• High-Voltage Outputs: 50 V
outputs with common-cathode clamp diodes for
• Output Clamp Diodes
switching inductive loads. The collector-current rating
of each Darlington pair is 500 mA. The Darlington
