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. 74h541d it OK to directly connect Sign up using Email and Password.

Linearly extrapolating to 5 V that becomes 3. Email Required, but never shown.

Worst case you don’t even meet the 0. In the datasheets you have to look for minimum high level input and maximum low level input.

A beginner style question. No, I know that “Schmidt” must be one of the most occurring names, I meant “Schmitt”. Post as a guest Name. 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?

But its output is a 3. The chip is a down-voltage converter and cannot be used at all for up converting.

It is pronounced more like “shmeet” would be in english, but means exactly the same as “smith”, 74hc541c refers to the profession today called “blacksmith”. Tony EE rocketscientist 62k 2 21 The input translator ir related to the output Vcc by having a threshold slightly more than Vcc so that a translator range of 2: I remember because it’s the only Schmitt I know.

Thanks for your reference document.

I don’t even know if it’s a common name in neighboring Germany.

Could you elaborate on this please Tony ” The former is of 0.

For input high a minimum of 3. The risk depends level of noise from ingress for long lines or, cross-talk, conducted noise or overshoot. So if you need a logic gate in there anyway, make it a HC T type and you get the 3. That would be 4. It doesn’t help that another local EE I know has the last name “Schmidt”.


Home Questions Tags Users Unanswered. This had a finite guaranteed logic high threshold sufficiently below 3. Good beginner questions; 3. I can never remember. This Microchip document shows some interesting ways to interface between 3. I just aim to do the voltage conversion. Before the industrial revolution, there were a lot of those around in Europe and elsewhere.

Luckily they used some variations on Ellis Island, or half of America would have been called Smith. Is it only leakage current that would be output in this instance? Olin Lathrop k dayasheet Peter H 1 3 Sign up or log in Sign up using Google. Links for you reference: So unless you are trying to do a closed-loop or loopback test? I may be misreading the datasheet, but I think you are: Low level input should be less than 1.


First off the noise immunity is imbalanced so that potential risk from ingress 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 other devices. The chip is a down-voltage converter hex buffer.

Whether that is sufficiently below 3.
