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 .

Product yln2004 in volume production only to support customers ongoing production. 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. Communications Equipment, Computers and Peripherals.

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. 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.

Each channel can have a working stream mA and withstand surges of mA. Selectors Simulators and Models. Menu Products Explore our product portfolio. 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 are showing a continuous load current of up to mA for each of its outputs.

Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout. Media Subscription Media Contacts. 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.
