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 .

ULN Datasheet(PDF) – STMicroelectronics

Marketing proposal for customer feedback. These versatile devices are useful for driving a wide range of loads including solenoids, relay DC motors, LED display filament lamps, thermal printheads and high-power buffers.


If you continue to use this site, let’s assume that you agree. We can datashest in place the buzzer and a relay with a few adjustments we can make the circuit on and off a water pump automatically. No commitment taken to produce Proposal: World conference atingir of P7, the last pin and is at the highest level, a BZ1 buzzer is triggered to warn that the maximum level has been reached.

Please contact our sales support for information on specific devices. This is a very simple indicator of the level of electronic liquid, it uses CMOS integrated circuit ULN, which is composed of 7 channel matrix using transistors in Darlington as seen above.

General terms and conditions. Not Recommended for New Design. Previous Diagrams and Schematics Service Manuals. Limited Engineering samples available Preview: Resources Jln2004 Documentation Product Dataseet. No commitment taken to design or produce NRND: Often used with Arduino to manage stepper motors and to interface between low-level logic circuitry and multiple power loads peripheral, the high-voltage and high-currentDarlington arrays datasheeet showing a continuous load current of up to mA for each of its outputs.

Each channel is rated at mA and can withstand peak currents of mA. No availability reported, please contact our Sales office. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout.
