Fonctionnalités et applications

The ULN2801A-ULN2805A 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.

Five 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 ; the ULN2803A has a 2.7 k, input resistor for 5 V TTL and CMOS ; the ULN2804A has a 10.5 k, input resistor for 6-15 V CMOS and the ULN2805A is designed to sink a minimum of 350 mA for standard and Schottky TTL where higher output current is required.

All types are supplied in a 18-lead plastic DIP with a copper lead from and feature the convenient input-opposite-output pinout to simplify board layout.
