Part Number: ULN2803C Tool/software: Hi
I am using this part in my design and for power budgeting i am not getting clarity on current consumption of this device. and how much voltage does this required. and if it is operating on 3.3V then how it is giving…

RE : ULN2803ADWR EOL device
We received the parts recently and the date code is 2314, which is over half of a year (Date:14 Sep 2022)for the PCN that announce the parts were discontinued. Is it possible…
Part Number: ULN2803C
Tool/software:
Pins 10 and 11 of the ULN2803CDWR device, must be left unconnected or can they be connected to GND like pin 9? What happens if pins 10 and 11 are connected to GND?
Hi M,
Yes, this current spike is expected. Each inductive load draws a little less than 80mA, so when all 4 channels are turned off at once, the integrated flyback diode on the COM pin dissipates the current back to the COM source, so your COM current…
Part Number: ULN2803C Tool/software: Hi Expert,
Please help to recommend suitable devices (P2P would be better) to replace ULN2803/ WSO-18/ NPN type/ Ioutmax=0.5A (From other competitor). Thanks.
Best Regards,
Ryker
Part Number: ULN2803C Tool/software: Hi T.I's. forum!
I'm looking for some information related to next Darlington Transistors Arrays part number "ULN2803ADKR-ND" this is provided by one of our customer' BOMs. I know this is a very old part number…
Part Number: ULN2803C Tool/software: Can the GND pin (9) be connected to a negative voltage other than circuit ground? I would like to use this device to drive 24V relays whose coils are connected to +/-12VDC. In this case the GND pin would be connected…
Part Number: ULN2803C I've reviewed the data sheet and schematics for the subject part. As I understand it - this part has no suppression diode connected to Pin 20. Is that correct?
If you feel my claim is incorrect, could you please draw the path…
Part Number: ULN2803C Tool/software: Hello,
The following diode specifications can be found in the ULN2803C data sheet: https://www.ti.com/lit/gpn/uln2803c
Output clamp current = 500mA (max)
Clamp forward voltage = 1.3V (typ)
Clamp reverse current =…
Part Number: ULN2803C Hello, I am a bit confused. I have been using the ULN2803 types in my designs and products for years. Unfortunately I have not received any information that the ULN2803ADW is being discontinued. Now the question for me is whether there…
