The ULN2803A with Darlington transistor array driver SOIC-18_300mil RoHS from Mixic is an integrated circuit (IC) that consists of eight Darlington transistor array drivers for interfacing between higher-current, higher-voltage components and the low-voltage logic of a microcontroller, processor, or driver. It is capable of sinking 500mA from the output pins and can withstand up to 50V source and sink voltage. The SOIC-18_300mil RoHS IC package is RoHS compliant and is lead-free and halogen-free. The package has eight pins and is widely used in various applications such as automotive, communication, industrial, instrumentation, computing, and more.
