Part Number: SN75451B Other Parts Discussed in Thread: ULN2003A , ULN2003LV Hi Team,
Customer would like to use SN75451 as a driver, but its temperature range is not enough(need -25C to 125C). I promote SN55451 as replacement, but seems it is a military…
Part Number: ULN2003A Other Parts Discussed in Thread: ULN2003LV Tool/software: Hello,
I was researching online various ways to achieve the same thing with the ULN2003A. I have this CMOS controller and I have received negative feedback so far from…
Part Number: ULN2003V12 Other Parts Discussed in Thread: ULN2003LV , Hi, TI Support Team
The table in the figure below is a comparison table between ULN2003V12 and ULN2003LV products.
This is a data downloaded from ti.com using the product compare…
Part Number: LM324LV Other Parts Discussed in Thread: ULN2003LV Dear Team,
May you give some TI suitable solution to replace MMBT3904?
ONSEMI,MMBT3904
Many Thanks,

Hi Seth,
Since the ULN2003A uses a Darlington Array structure, its VCE,sat is relatively constant with respect to current compared to a resistive or MOSFET structure, so the ULN2003A output LOW voltage of 0.65V is expected. To lower this output low…
Hi Hsu Cheng,
Thanks for reaching out on E2E!
This looks like a low side LED driver. I recommend taking a look at the TPL7407LA or the ULN2003LV for this application.
Thanks,
Arthur Huang
Hi Arthur,
I am using this part to control 8 fiber optic transmitters simultaneously in a 5V circuit, but in a noisy (high voltage) surrounding.
This is why I prefer not to use 5V parts like ULN2003LV or SN75452 that have a 5.5V input maximum rating…
Hello,
Thank you very much for your link !
I notice that my image in my last post hadn't been uploaded. So here, a part of my design :
As you will see, it is derived from the fuel tank boostpack, but with a dedicated power ground to respect the…
Hung,
ULN2003A shouldn't be used beyond ABS max conditions, although it would more than likely survive for such short time. Regardless we can't recommend the customer to do this.
One solution is to parallel multiple channels which will be <=400mA…
Hi Nandini,
There are two potential solutions that I can think of:
1: This application seems more application for a low side switch. Would a device such as the TPL7407LA or the ULN2003LV work here instead? What is your load current?
2: Maybe a signal…
