DATASHEET ULN2004 PDF

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 is 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. This water level indicator with ULN is very simple and requires few electronic components. Communications Equipment, Computers and Peripherals.

Distributor Name Region Stock Min. 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. Support Center Video Center.

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. 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.

Responsibility Site – Privacy Policy. Each channel can have a working stream mA and withstand surges of mA. 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. Computers and Peripherals Data Center. Often used with Arduino to manage stepper motors and to interface between low-level logic circuitry and multiple power loads peripheral, datadheet high-voltage and high-currentDarlington arrays are showing a continuous load current of up to mA for each of its outputs.
