Description
Seven-channel NPN Darlington array used to interface logic ciruits (i.e., microcontroller) to high-voltage, high-current devices like lamps, relays, and solenoids. The ULN2003A is capable of driving 500 mA into a single channel, up to 250 mA per channel with four channels active, and up to 150 mA with all seven channels active. ULN2003A outputs use clamp diodes for transient suppression to protect low-power microcontroller circuitry.

The ULN2003A is the replacement for the ULN2803A when using the Prop-1 Trainer Board or when using P7 (Prop-1) or P15 (Prop-2 and Prop-SX) for serial communications with devices like the AP-8, DC-16, FC-4, and RC-4.
