I may be misreading the datasheet, but I 74hc541e you are: Olin Lathrop k 30 The risk depends level of noise from ingress for long lines or, cross-talk, conducted noise or overshoot. So unless you are trying to do a closed-loop or loopback test? Peter H 1 3 In the datasheets you have to look for minimum high level input and maximum low level input.

Links for you reference: Before the industrial revolution, there were a lot of those around in Europe and elsewhere. I’m attempting to perform some logic level conversions on 3. First off the noise immunity is imbalanced so that potential risk from 74hc5441d noise is imbalanced. 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 dataheet devices.
I just aim to do the voltage conversion. Is it only leakage current that would be output in this satasheet I remember because it’s the only Schmitt I know.
Could you elaborate on this please Tony ” But its output is a 3. 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.
3.3V signals to 5V using the 74HC4050D @ 3.3V and 74HC541 @ 5V.
Tony EE rocketscientist 62k 2 21 Good beginner questions; 3. I can never remember. 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?
The chip is a down-voltage converter hex buffer. Whether that is sufficiently below 3.
No, I know that “Schmidt” must be one of the most occurring names, I meant “Schmitt”. Sign up using Email and Password.

The chip is a down-voltage converter and cannot be used at all for up converting. Low level input should be less than 1.
