Overview
ULN2002A, ULN2003A, ULN2003AI ULQ2003A, ULN2004A, ULQ2004A SLRS027R – DECEMBER 1976 – REVISED FEBRUARY 2024 ULN200x, ULQ200x High-Voltage, High-Current Darlington Transistor Arrays 1 Features • 500-mA-Rated Collector Current (Single Output) • High-Voltage Outputs: 50 V • Output Clamp Diodes • Inputs Compatible With Various Types of Logic • Relay-Driver Applications 2 Applications • Relay Drivers • Stepper and DC Brushed Motor Drivers • Lamp Drivers • Display Drivers (LED and Gas Discharge) • Line Drivers • Logic Buffers 3 Description The ULx200xA devices are high-voltage, high-current Darlington transistor arrays.
Each consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads.
The collector-current rating of a single Darlington pair is 500 mA.
The Darlington pairs can be paralleled for higher current capability.
Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers.
For 100-V (otherwise interchangeable) versions of the ULx2003A devices, see the SLRS023 data sheet for the SN75468 and SN75469 devices.
The ULN2002A device is designed specifically for use with 14-V to 25-V PMOS devices.
Each input of this device has a Zener diode and resistor in series to control the input current to a safe limit.
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.
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 required input current of the ULx2004A device is below that of the ULx2003A devices, and the required voltage is less than that required by the ULN2002A device.
