ULN2803 IC in PakistanThe 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
