ULN2001A Datasheet PDF - ST Microelectronics

●The ULN2001A is a high current Bipolar Transistor Array containing seven open-collector Darlington pairs with common emitters. Each channel rated at 500mA and can withstand peak currents of 600mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout. It is useful for driving a wide range of loads including solenoids, relays DC motors, LED displays filament lamps, thermal print-heads and high power buffers.

● High voltage

● Integrated suppression diodes for inductive loads

● Outputs can be paralleled for higher current

● TTL/CMOS/PMOS/DTL compatible inputs

● Inputs pinned opposite outputs to simplify layout
