Product Summary
The uln2804ae3 is an Eight Darlington Array. The uln2804ae3 each contain eight Darlington transistors with common emitters and integral suppression diodes for inductive loads. Each Darlington features a peak load current rating of 600mA (500mA continuous) and can withstand at least 50V 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 uln2804ae3 has a 10.5kΩ input resistor and zener for 14-25V PMOS; the uln2804ae3 has a 2.7kΩ input resistor for 5V TTL and CMOS ; the uln2804ae3 has a 10.5kΩ input resistor for 6-15V CMOS and the uln2804ae3 is designed to sink a minimum of 350mA 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 pin out to simplify board layout.
