So if you need a logic gate in there anyway, make it a HC T type and you get the 3. The chip is a down-voltage converter and cannot be used at all for up converting.
First off the noise immunity is imbalanced so that potential risk from ingress noise is imbalanced.

Luckily they used some variations on Ellis Island, or half of America would have been called Smith. I just aim to do the voltage conversion.

Thanks for your reference document. The former is of 0. Sign up using Facebook. Good beginner questions; 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. I don’t even know if it’s a common name in neighboring Germany. Worst case you don’t even meet the 0. So unless you are trying to do a closed-loop or loopback test? Before the industrial revolution, there were a lot of those around in Datasneet and elsewhere. Sign up or log in Sign up using Google. It doesn’t help that another local EE I know has the last name “Schmidt”.

But its output is a 3. I remember because it’s the only Schmitt I know.
Home Questions Tags Users Unanswered. The input translator ir related to datashee output Vcc by having a threshold slightly more than Vcc so that a translator range of 2: No, Dtasheet know that “Schmidt” must be one of the most occurring names, I meant “Schmitt”. Peter H 1 3 Sign up using Email and Password. This had a finite guaranteed logic high threshold sufficiently below 3. I’m attempting to perform some logic level conversions on 3. Email Required, but never shown. Linearly extrapolating to 5 V that becomes 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. Post as a guest Name.
This Microchip document shows some interesting ways to interface between 3. I guess my question is without resistors connected how would one know whether dayasheet safe to connect the outputs of the 74HCD to the inputs of the 74HC as this chip can do the logic conversion? Is it only leakage current that would be output in this instance?
The chip is a down-voltage converter hex buffer.
74HCD (Philips) – Octal buffer/line driver; 3-state
Whether that is sufficiently below 3. In the datasheets you have to look for minimum high level input and maximum low level input. Low level input should be less than 1. 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”.
Links for you reference: I may be misreading the datasheet, but I think you are: A beginner style question. The risk depends level of noise from ingress for long lines or, cross-talk, conducted noise or overshoot.

Tony EE rocketscientist 62k 2 21 For input high a minimum of 3. I can never remember.
That would be 4.
