ULN2001A , ULN2002A , ULN2003A , ULN2004A IC CHEAP.
DESCRIPTION
The ULN2001A, ULN2002A, ULN2003A and ULN2004A are 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.
General Purpose
- ULN2001A; DTL, TTL, PMOS, CMOS
- ULN2002A; 14-25V PMOS
- ULN2003A; 5V TTL, CMOS
- ULN2004A; 6–15V CMOS, PMOS
These versatile devices are useful for driving a wide range of loads including
- Solenoids,
- Relays DC motors,
- LED displays filament lamps,
- Thermal print-heads and
- High power buffers.
The ULN2001A/2002A/2003A and 2004A are supplied in 16 pin plastic DIP packages with a copper leadframe to reduce thermal resistance. They are available also in small outline package (SO-16) as ULN2001D/2002D/2003D/2004D.
