ULN2002A/ ULN2003A/ ULN2004A
HIGH VOLTAGE, HIGH CURRENT
DARLINGTON TRANSISTOR ARRAYS
Description
Pin Assignments
The ULN2002A, ULN2003A and ULN2004A are high voltage, high
current Darlington arrays each containing seven open collector
common emitter pairs. Each pair is rated at 500mA. Suppression
diodes are included for inductive load driving, the inputs and outputs
are pinned in opposition to simplify board layout.
