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 .

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.

Communications Equipment, Computers and Peripherals. 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.


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. Buy Direct Add to cart. 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.
