I don’t even know if it’s a common name in neighboring Germany. So if you need a logic gate in there anyway, make it a HC T type and you get the 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. First off the noise immunity is imbalanced so that potential risk from ingress noise is imbalanced. 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”.

This Microchip document shows some interesting ways to interface between 3.

The risk depends level of noise from ingress for long lines or, cross-talk, conducted noise or overshoot.

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.

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. Linearly extrapolating to 5 V that becomes 3. I may be misreading the datasheet, but I think you are: But its output is a 3. Is it only leakage current that would darasheet output in this instance?

For input high a minimum of 3. No, I know that “Schmidt” must be one of the most occurring names, I meant “Schmitt”.

The chip is a down-voltage converter hex buffer.

I remember because it’s the only Dataaheet I know.

This had a finite guaranteed logic high threshold sufficiently below 3.

The former is of 0. Could you elaborate on this please Tony ” Post as a guest Name.


Email Required, fatasheet never shown. The input translator ir related to the output Vcc by having a threshold slightly more than Vcc so that a translator range of 2: Olin Lathrop k 30 Before the industrial revolution, there were a lot of those around in Europe and elsewhere.

A beginner style question. That would be 4. I can never remember. Is it OK to directly connect Whether that is sufficiently below 3. It doesn’t help that another local EE I know has the last name “Schmidt”. In the datasheets you have to look for minimum high level input and maximum low level input. Worst case you don’t even meet the 0. 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?

Luckily they used some variations on Ellis Island, or half of America would have been called Smith. So datssheet you are trying to do a closed-loop or loopback test?

Low level input should be less than 1. I just aim to do the voltage conversion. Links for you reference: Sign up or log in Sign up using Google.
