Texas Instruments ULN2004ADR

Texas Instruments ULN2004ADR Environmental and export classification status description

: The Texas Instruments ULN2004ADR is a high-voltage, high-current Darlington transistor array. It consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. 2. Functions: - The ULN2004ADR is used as a relay-driver, LED driver, stepper motor driver, and general-purpose driver for high current loads. - It provides means for the control of output loads up to 500 mA of load current per channel. - The Darlington pairs can be paralleled for higher current capability. 3. Applications: - Motor controls - Printer-head drivers - LED displays - Copier machines - Stepper motor drivers 4. Alternative Parts: Alternative parts to the ULN2004ADR include Texas Instruments' ULN2003ADR and ULN2002ADR, which offer a different number of Darlington pairs based on the project's requirements. 5. Embedded Modules: The ULN2004ADR is often integrated into various embedded systems for driving inductive loads reliably and efficiently due to its high-current and high-voltage capabilities.
