Seven channel Darlington array ST ULQ2004A designed for driving LED displays filament lamps and thermal print heads
Product Overview
The ULQ2001, ULQ2003, and ULQ2004 are high voltage, high current Darlington arrays, each featuring seven open collector Darlington pairs with common emitters. These devices are designed for driving a wide range of loads including solenoids, relays, DC motors, LED displays, filament lamps, thermal print-heads, and high power buffers. Key features include an extended temperature range, 500 mA output current per driver (600 mA peak), and integrated suppression diodes for inductive loads. The inputs are pinned opposite the outputs to simplify board layout, and they are compatible with TTL, CMOS, PMOS, and DTL logic families. Automotive Grade versions are available for specific applications.
