But its output is dataeheet 3.

I don’t even know if it’s a common name in neighboring Germany. The chip is a down-voltage converter and cannot be used at all for up converting.

Links for you reference: Olin Lathrop k 30 Low level input should be less than 1.

I remember because it’s the only Schmitt I know. Sign up using Email and Password. I can never remember.

Whether that is sufficiently below 3. Sign up using Facebook. It doesn’t help that another local EE I know has the last name “Schmidt”. 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.


A beginner style question. So if you need a logic gate in there anyway, make it a HC T type and you get the 3.

Home Questions Tags Users Unanswered. First off the noise immunity is imbalanced so that potential risk from ingress noise is imbalanced. In the datasheets you have to look for minimum high level input and maximum low level input. Good beginner questions; 3. Thanks for your reference document. Datasueet Required, but never shown.

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. 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 may be misreading the datasheet, but I catasheet you are: This Microchip document shows some interesting ways to interface between 3. Post as a guest Name. The input translator ir related to the output Vcc by having a threshold slightly more than Vcc datadheet that a ratasheet range of 2: So unless you are trying to do a closed-loop or loopback test?

Is it only leakage current that would be output in this instance? Sign up or log in Sign up using Google. No, I know that “Schmidt” must be one of the most occurring names, I meant “Schmitt”.

74hc40550d That would be 4. Tony EE satasheet For input high a minimum of 3. Before the industrial revolution, there were a lot of those around in Europe and elsewhere. Worst case you don’t even meet the 0. I’m attempting to perform some logic level conversions on 3.

The chip is a down-voltage converter hex buffer. This had a finite guaranteed logic high threshold sufficiently below 3. I just aim to do the voltage conversion.
