Product Description

Product Overview

The ULN2803-MS is a high-voltage, high-current Darlington transistor array featuring eight open-collector, common-emitter pairs, each capable of 500mA. It includes suppression diodes for inductive load driving and opposing input/output pins for simplified board layout. This versatile device is suitable for driving a wide range of loads such as solenoids, relays, DC motors, LED displays, filament lamps, thermal print-heads, and high-power buffers. Available in SOP18, SSOP24, and QSOP24 packages.
