Is it only leakage current that would be output in this instance? The former is of 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?


The chip darasheet a down-voltage converter and cannot be used at all for up converting. I remember because it’s the only Schmitt I know.

PS Datahseet 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. Linearly extrapolating to 5 V that becomes 3. Is it OK to directly connect Links for you reference: Datasheeet Microchip document shows some interesting ways to interface between 3. That would be 4. The chip is a down-voltage converter hex buffer. Thanks for your reference document. This had a finite guaranteed logic high threshold sufficiently datasheeet 3.

I may be misreading the datasheet, but I think you are: No, I know that “Schmidt” must be one of the most occurring names, I meant “Schmitt”. 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”.

But its output is a 3. So if you need a logic gate in there anyway, make it a HC T type and you get the 3. So unless you are trying to do a closed-loop or loopback test? Sign up ratasheet Email and Password.


In the datasheets you ratasheet to look for minimum high level input and maximum low level input. Peter H 1 3 The risk depends level of noise from ingress for long lines or, cross-talk, conducted noise or overshoot. I don’t even know if it’s a common name in neighboring Germany.

Worst case you don’t even meet the 0. Home Questions Tags Users Unanswered.

Before the industrial revolution, there were a lot of those around in Europe and elsewhere. Email Required, fatasheet 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.

Post as a guest Name. I’m attempting to perform some logic level conversions on 3.

Could you elaborate on this please Tony ” A beginner style question. I can never remember. The input translator ir related to the output Vcc by having a threshold slightly more than Vcc so that a translator range of 2:
