Post as a guest Name. It is pronounced more like “shmeet” would be in english, but means exactly the same as “smith”, which refers to the profession today called “blacksmith”. I don’t even know if it’s a common name in neighboring Germany.
Is it only leakage current that would be output in this instance? So if you need a logic gate in there anyway, make it a HC T type and you get the 3. I can never remember.
In the datasheets you have to look for minimum high level input and maximum low level input. Whether that is sufficiently below 3. Sign up using Facebook. Luckily they used some variations on Ellis Island, or half of America would have been called Smith. That would be 4.
Tony EE rocketscientist 62k 2 74yct541d What should I be looking for in terms of the datasheets when determining these things in my case I don’t really aim to source or sink current to other devices. I may be misreading the datasheet, but I think you are: A beginner style question. It doesn’t help that another local EE I know has the last name “Schmidt”. The chip is a down-voltage converter hex buffer.
I remember because it’s the only Schmitt I know.
3.3V signals to 5V using the 74HC4050D @ 3.3V and 74HC541 @ 5V.
The chip is a down-voltage converter and cannot be used at all for up converting. I’m attempting to perform some logic level conversions on 3. I guess my question is without resistors connected how would one know whether it’s safe to connect the outputs of the 74HCD to the inputs of the 74HC as this chip can do the logic conversion? Peter H 1 3 Home Questions Tags Users Unanswered. PS I’m aware of that the maximum current into these devices Icc is about 50ma and a max output of a particular pin Io is around ma.
Is it OK to directly connect Sign up or log in Sign up using Google. Could you elaborate on this please Tony ” First off the noise immunity is imbalanced so that potential risk from ingress noise is imbalanced. Worst case you don’t even meet the 0. This had a finite guaranteed logic high threshold sufficiently below 3.
Links for you reference: Sign up using Email and Password. Low level input should be less than 1.

Thanks for your reference document. The risk depends level of noise from ingress for long lines or, cross-talk, conducted noise or overshoot.
Good beginner questions; 3. Before the industrial revolution, there were a lot of those around in Europe and elsewhere.
