The ULQ2801-ULQ2804 are ST's eight Darlington arrays, with extended temperature range (-40 to 105 °C), output current up to 500 mA, output voltage up to 50 V, integrated suppression diodes, versions for all popular logic families, outputs can be paralleled, inputs and outputs are opposite each other to simplify PCB layout.
The ULQ2801-ULQ2804 series consists of eight Darlington transistors per package with common emitters and integral suppression diodes designed 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.
