Is it only leakage current that would be output in this instance? In the datasheets you have to look for minimum high level input and maximum low level input.
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”. Sign up using Email and Password.
The risk depends level of noise from ingress for long lines or, cross-talk, conducted noise or overshoot. Links for you reference: It doesn’t help that another local EE I know has the last name “Schmidt”.
That would be datasheft. Peter H 1 3 But its output is a 3.

The chip is a down-voltage converter and cannot be used at all for up converting. I don’t even know if it’s a common name in neighboring Germany.
I just aim to do the voltage conversion. I may be misreading the datasheet, but I think you are: Before the industrial revolution, there were a lot of those around in Europe and elsewhere. Linearly extrapolating to 5 V that becomes 3. Low level input should be less than 1. So if you need a logic gate in there anyway, make it a HC T type and you get the 3.
This Microchip document shows some interesting ways to interface between 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? The former is of 0.
I remember because it’s the only Schmitt I know.

Post as a guest Name. I can never remember. A beginner style question. For input high a minimum of 3. Tony EE rocketscientist Thanks for your reference document.
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. Home Questions Tags Users Datasheft. Sign up using Facebook. Olin Lathrop k 30 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. 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. So unless you are trying to do a closed-loop or loopback test?
First off the noise immunity is imbalanced so that potential risk from ingress noise is imbalanced.
