The ULx2004A devices have a 10.5-kΩ series base resistor to allow operation directly from CMOS devices that use supply voltages of 6 V to 15 V. The range of current could be increased by using the two pins for the same load. (each driver) ULN2002 (each driver) ULN2003 (each driver) ULN2004 (each driver) Pin configuration ULN2001, ULN2002. The versions interface to all common logic families: ULN2001 (general purpose, DTL, TTL. are pinned opposite the outputs to simplify board layout. The current handling system is also 500mA for each input. ULN2003, ULN2004 Seven Darlington arrays Datasheet -production data Features. It comes in another version with a voltage range of 100V. The ULx2003A devices have a 2.7-kΩ series base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS devices. It is able to handle the high DC voltage range of about 50V maxima. Each input of this device has a Zener diode and resistor in series to control the input current to a safe limit. The ULN2002A device is designed specifically for use with 14-V to 25-V PMOS devices. For 100-V (otherwise interchangeable) versions of the ULx2003A devices, see the SLRS023 data sheet for the SN75468 and SN75469 devices.

Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers. The Darlington pairs can be paralleled for higher current capability. When operating in 3-pin mode these LEDs are driven by the SN74HC595, and when operating in 8-pin mode these LEDs are being driven directly by the MSP430 GPIO pins.

The collector-current rating of a single Darlington pair is 500 mA. The ULN2003 is one of the most common motor driver ICs, consisting of an array of 7 Darlington transistor pairs, each pair is capable of driving loads of up. BOOSTXL-ULN2003 Dual Stepper Motor Driver BoosterPack Hardware 2.4.3 LEDs The four on-board LEDs provide visual feedback for the IN1 through IN4 signals. Each consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The elecrow uln2003 stepper motor driver board is using the uln2003 darlington arrays to drive the 4phase 5wire stepper motor 5 12 v. The ULx200xA devices are high-voltage, high-current Darlington transistor arrays. arduino-tutorial/) drivers that work great with many stepper motors.
