ULN2801A, ULN2802A, ULN2803A, ULN2804A Eight Darlington arrays Datasheet - production data Description The ULN2801A, ULN2802A, ULN2803A and ULN2804A each contain eight Darlington transistors with common emitters and integral suppression diodes for inductive loads. Each Darlington features a peak load current rating of 600 mA (500 mA continuous) and can withstand at least 50 V in the OFF state. Outputs may be paralleled for higher current capability. DIP-18 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 k input resistor and Zener for 14-25 V PMOS Features the ULN2803A has a 2.7 k input resistor for 5 V TTL and CMOS the ULN2804A has a 10.5 k Eight Darlington transistors with common input resistor for 6-15 V CMOS. emitters All types are supplied in an 18-lead plastic DIP Output current to 500 mA with a copper lead form and feature the Output voltage to 50 V convenient input-opposite-output pinout to Integral suppression diodes simplify board layout. Versions for all popular logic families Output can be paralleled Inputs pinned opposite outputs to simplify board layout Table 1.
