DESCRIPTION. The ULNA, ULNA, ULN and. ULNA are high voltage, high current darlington arrays each containing seven open collector. The UTC ULN are high-voltage, high-current darlington drivers comprised of seven NPN darlingto pairs. All units feature integral clamp diodes for switching. For V (otherwise interchangeable) versions of the ULxA devices, see the SLRS data sheet for the SN and SN devices. The ULNA .

Communications Equipment, Computers and Peripherals. Each channel is rated at mA and can withstand peak currents of mA.
Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout. The versions interface to all common logic families: These versatile devices are useful for driving a wide range of loads including solenoids, relay DC motors, LED display ulb2004 lamps, thermal printheads and high-power buffers.
