Bruges bl.a. som driver til stepmotor og store LED displays.
ULN2004 krævere mindre strøm på inputpin end ULN2003, for at drive den samme belastning.
The ULN2001, ULN2002, ULN2003 and ULN 2004 are high voltage, high current Darlington arrays each containing seven open collector Darlington pairs with common emitters. Each channel rated at 500 mA and can withstand peak currents of 600 mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout.
Seven Darlingtons per package
Output current 500 mA per driver (600 mA peak)
Output voltage 50 V
Integrated suppression diodes for inductive loads
Outputs can be paralleled for higher current
TTL/CMOS/PMOS/DTL compatible inputs
Inputs pinned opposite outputs to simplify layout
