XL2803AG – Darlington Transistor Array – Xinluda
The Xinluda XL2803AG is an 8-channel, 50V/500mA NPN Darlington transistor array in a SOP-18 (300mil) package, part of the industry-standard ULN2803 family, with integrated output clamp diodes for driving inductive loads.
The XL2803AG from Xinluda is an 8-channel high-current/high-voltage NPN Darlington transistor array, a member of the industry-standard ULN2803 family. Each of its eight Darlington pairs can sink up to 500 mA at output voltages up to 50 V, and integrated common-cathode output clamp (flyback) diodes make the device suitable for switching inductive loads such as relays, solenoids, and stepper motors directly from microcontroller, TTL, or 5 V CMOS logic outputs. It is supplied in a SOP-18 (300 mil, wide-body) surface-mount package.
