Description:
The   ULN2803A   is   a   high-voltage,   high-current   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 has a 2.7-kΩ series base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS devices.
Features:
  • 500-mA Rated Collector Current (Single Output)
  • High-Voltage Outputs...50 V
  • Output Clamp Diodes
  • Inputs Compatible With Various Types of Logic
  • Relay Driver Applications
  • Compatible with ULN2800A Series
