ULN2804A Darlington Transistor Array IC

ULN2804A Darlington Transistor Array IC

The ULN2804A is a contain eight Darlington transistors with common emitters and integral suppression diodes for inductive loads. Each Darlington features a peak load current rating of 600mA (500 mA continuous) and can withstand at least 50V in the OFF state. Outputs may be paralleled for higher current capability. Four versions are available to simplify interfacing to standard logic families: the ULN2801A is designed for general purpose applications with a current limit resistor; the ULN2802A has a 10.5 kΩ input resistor and Zener for 14-25 V PMOS; the ULN2803A has a 2.7 kΩ input resistor for 5 V TTL and CMOS; the ULN2804A has a 10.5 kΩ input resistor for 6-15 V CMOS. All types are supplied in an 18-lead plastic DIP package.
