Product Description
Product Overview
The UMW ULN2003 is a high-voltage, high-current Darlington driver IC featuring 7 NPN Darlington pairs. It is designed for applications requiring direct connection to TTL, CMOS, and PMOS logic, eliminating the need for logic buffers. With a wide operating voltage range, high output voltage (up to 50V), and high output current (up to 500mA), it is suitable for driving various loads including relays, lamps, and motors. Integrated clamp diodes protect against inductive load switching.
