TechnologiesThe Unisonic Technologies ULN2003G-S16-R is a 16 Darlington transistor array driver designed for use in high-current/high-voltage applications. The device integrates a 500mA rated Darlington transistor array with a Schottky diode array and a common-emitter amplifier. It has a medium power dissipation of 1W and a wide operating voltage environment of 10 to 50V. The ULN2003G-S16-R is packaged in a 150-mil SOP (small outline package) measuring 3.9 mm x 4.9 mm, and is compliant with RoHS (Restriction of Hazardous Substances) standards. It is well-suited for use in controlling things such as stepper motors, drivers, relays, and solenoids, and can be used for interface and level shifting applications.
