The device consists of(Single Output)eight NPN Darlington pairs that feature high-voltage High-Voltage Outputs: 50 Voutputs withcommon-cathodeclampdiodes for Output Clamp Diodes switching inductive loads. The collector-current ratingof each Darlington pair is 500 mA. The Darlington Inputs Compatible With Variouspairs may be connected in parallel for higher currentTypes of Logiccapability. Relay-Driver ApplicationsApplications include relay drivers, hammer drivers, Compatible with ULN2800A Serieslamp drivers, display drivers (LED and gasdischarge), line drivers, andlogic buffers. The2 Appl i ca t i o n sULN2803A device has a 2.7-k series base resistorfor each Darlington pair for operation directly with Relay DriversTTL or 5-V CMOS devices.
