Plastic-Encapsulate Darlington Transistors
ULN2003
DARLINGTON TRANSISTOR (NPN)
Description
Features
ULN2003 is high voltage, high current darlington
arrays each containing seven open collector darlington
pairs with common emitters. Each channel rated at
500mA and can withstand peak currents of 600mA.
Suppression diodes are included for inductive load
driving and the inputs are pinned opposite the outputs
to simplify board layout.
Applications include relay drivers, hammer drivers,
lamp drivers, display drivers (LED and gas discharge),
line drivers, and logic buffers. The ULN2003 device
has a 2.7-kΩ series base resistor for each Darlington
pair for operation directly with TTL or 5-V CMOS
devices.
