Level shiffter (3.3V / 5V) for controlling transistors












2














Is it possible to control the base of the transistor using the level shift chip (3.3V / 5V)?
I want to use the SN74AHCT125 level shift chip.



Transistor BC337-16

    It is possible to get bad results too unless you are more specific on your configuration and output spec limits.,

    Please edit your question to include a schematic of what you're really trying to do. As pointed out in the answer, a level-shifter is almost certainly unnecessary.

There generally is no need to use a level shifter to control a BJT transistor, as long as the high output level is higher than the required $V_{rm BE}$ (1.2V for your BC337-16 transistor, with $I_{rm C} = 300 rm mA$ and $V_{rm CE} = 1 rm V$). WHat are you trying/willing to do?

            What visual should I use to simply compare current year value vs last year in Power BI desktop

            Image
            0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?

            How to ignore python UserWarning in pytest?

            up vote 1 down vote favorite I am using openpyxl for parsing .xlsm files, and pytest for testing. When I open a file, I get the: OpenPyxl -> UserWarning: Data Validation extension is not supported and will be removed That is not really a problem bcs. program works and I can't change the .xlsm file to fix that. But... When I run pytest with something like: def test_wrong_file_format(): assert check_excel(open_excel('file.xlsm')) == True I will get the warning i mentioned altought check_excel(open_excel('file.xlsm')) returns True and the test should suceed... Is there a nice way to tell the pytest that "It's not a bug it's a feature" and tests should pass even when they get this warning? Is there other way than using something like: with pytest.warns(UserWarning): ...
