ULN2803A DARLINGTON TRANSISTOR ARRAY - DIP 18 - USA SHIPPING (NEW SURPLUS)

Description

ABOUT THE ITEM: These IC's are new but have been sitting in a warehouse for years. They are in OEM tubes and will be packaged for shipment in a tube section. Standard 18-pin DIP package, which has been discontinued by some manufacturers. Here's some basic info I lifted from a data sheet:
"The ULN2803A device is a 50 V, 500 mA Darlington
transistor array. The device consists of eight NPN
Darlington pairs that feature high-voltage outputs with
common-cathode clamp diodes for switching
inductive loads. The collector-current rating of each
Darlington pair is 500 mA. The Darlington pairs may
be connected in parallel for higher current capability.
Applications include relay drivers, hammer drivers,
lamp drivers, display drivers (LED and gas
discharge), line drivers, and logic buffers. The
ULN2803A device has a 2.7-kΩ series base resistor
for each Darlington pair for operation directly with
TTL or 5-V CMOS devices."
If you need more details, the data sheet is available online. I'm happy to answer questions that pertain to this listing but cannot offer any technical advice or assistance.
