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 .

Indicator Circuit water level using the ULN
Suppression diodes are included for inductive load driving and the uln200 are pinned opposite the outputs to simplify board layout.
ST Code of Conduct Blog. Computers and Peripherals Data Center. We can put 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 design or produce NRND: Product is in design stage Target: 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. Product is in design feasibility stage. Support Center Video Center. Previous Diagrams and Schematics Service Manuals.
Product is in volume production 0. No availability reported, please contact our Sales office. Buy Direct Add to cart. Clovis We are on Google Clovis. Please contact our sales support for information on specific devices. The versions interface to all common logic families: 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.
The power supply can be between 9 E Volts 12 Volts and the current can be less than 1 Ampere. The operation is simple, and increasing the level of water in the tank, water comes into contact with the ends P1 to P7 and so, cause the pins 7 LEDs light up their channels in sequence.
