IC zum schalten von Relais! (Hilfe gesucht)

verfasst von Stoffel(R), 08.01.2006, 16:53

Für deine Anwendung müssten die IC\'s ULN2801A ULN2802A ULN2803A ULN2804A ULN2805A gehenDas Datenblatt sagt:The ULN2801A-ULN2805Aeach contain eight dar-lingtontransistors with common emitters and inte-gralsuppression diodes for inductive loads. Eachdarlington features a peak load current rating of600mA (500mA continuous) and can withstand atleast 50V in the off state. Outputsmaybe paralleledfor higher current capability.Five versions are available to simplify interfacing tostandard logic families : the ULN2801Ais designedfor general purpose applicationswith a current limitresistor ; the ULN2802Ahas a 10.5kW input resistorand zenerfor 14-25V PMOS; the ULN2803Ahas a2.7kW input resistor for 5V TTL and CMOS ; theULN2804A has a 10.5kW input resistor for 6-15VCMOS and the ULN2805A is designed to sink aminimum of 350mA for standard and Schottky TTLwhere higher output current is required.Grüße,Stoffel
