Product Information

ULN2001A, ULN2002A, ULN2003A, ULN2004A DARLINGTON TRANSISTOR ARRAYS SLRS027 – DECEMBER 1976 – REVISED APRIL 1993 HIGH-VOLTAGE HIGH-CURRENT DARLINGTON TRANSISTOR ARRAYS D D D D D D 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 Designed to Be Interchangeable With Sprague ULN2001A Series D OR N PACKAGE (TOP VIEW) description 1B 2B 3B 4B 5B 6B 7B E 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 1C 2C 3C 4C 5C 6C 7C COM The ULN2001A, ULN2002A, ULN2003A, and ULN2004A are monolithic 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 may 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, see the SN75465 through SN75469. The ULN2001A is a general-purpose array and can be used with TTL and CMOS technologies. The ULN2002A is specifically designed for use with 14- 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 ULN2003A has a 2.7-kΩ series base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS devices. The ULN2004A has a 10.5-kΩ series base resistor to allow its operation directly from CMOS devices that use supply voltages of 6 to 15 V. The required input current of the ULN2004A is below that of the ULN2003A, and the required voltage is less than that required by the ULN2002A. logic symbol† 9 CLAMP 1 1B 2B 3B 4B 5B 6B 7B 2 3 4 5 6 7 16 15 14 13 12 11 10 COM 1C 2C 3C 4C 5C 6C 7C logic diagram 9 1B 1 16 COM 1C 2B 2 15 2C 3B 3 14 3C 4B 4 13 4C † This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12. 5B 5 12 5C 6B 6 11 6C 7B 7 10 7C PRODUCTION DATA information is current as of publication date.
