Overview
The DS2003CMX/NOPB-NS, produced by Texas Instruments (now part of the National Semiconductor portfolio), is a high current/voltage Darlington driver. This device consists of seven high-gain NPN Darlington transistor pairs, each featuring common emitter and open collector outputs. It is designed to handle high output voltages (VCE = 50V) and high output currents (IC = 350 mA), making it suitable for a variety of interface applications including solenoids, relays, lamps, small motors, and LEDs.
