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?

            Ne doit pas être confondu avec trompette de poche. Trompette piccolo en si bémol, avec des branches d'embouchure différentes pour le si bémol (la plus courte) ou la (la plus longue) Trompette piccolo La trompette piccolo est la plus petite de la famille des trompettes. Elle joue une octave plus haut que la trompette standard en si bémol. La plupart des trompettes piccolo sont conçues pour jouer dans les deux tonalités de si bémol ou la, en utilisant une branche d'embouchure différente pour chaque tonalité. Le tube de la trompette piccolo en si bémol a une longueur moitié de celle de la trompette normale en si bémol. Des trompettes piccolo en sol, fa, ut sont également fabriquées, mais elles sont rares. La trompette soprano en ré, aussi connu comme la « trompette Bach », a été inventée vers 1890 par le facteur belge Victor-Charles Mahillon pour jouer les parties hautes de la trompette dans la musique de Bach et Haendel. La trompette piccolo moderne permet aux

            Slow SSRS Report in dynamic grouping and multiple parameters

            Image
            0 I have developed a report which has 5 dynamic row groups from where users can choose in parameter selection. The report has 12 parameters so that user can get required information as per their parameter choice. Each parameter has multi value selection option with numerous lists of values (example: Customer parameter has 35,000 values and Item parameter has 2,500 values). Now, the report takes huge time to load parameter values as well as slow in preview (although, server resource is adequate). I am looking for a solution to improve the parameter selection performance without reducing the number of parameter and dynamic grouping sql-server reporting-services ssrs-2012 share | improve this question
