TOSHIBA Bipolar Digital Integrated Circuit Silicon Monolithic
ULN2803APG, ULN2803AFWG, ULN2804APG, ULN2804AFWG
8ch Darlington Sink Driver
The ULN2803APG / AFWG Series are high−voltage,
high−current darlington drivers comprised of eight NPN
darlington pairs.
All units feature integral clamp diodes for switching inductive
loads.
Applications include relay, hammer, lamp and display (LED)
drivers.
Features
• Output current (single output)
500 mA (max)
• High sustaining voltage output
50 V (min)
• Output clamp diodes
• Inputs compatible with various types of logic.
• Package Type−APG : DIP−18pin
• Package Type−AFWG : SOP−18pin
