MY reasoning is fairly simple 1. There are 3 or 4 terminal switchers that are either boost, buck and or variable for both topologies as well as boost-buck which is neat because Vsupply can swing about the output voltage. Apologies, should have mentioned datasjeet power source. I remember reading a datsaheet where GrumpyMike explained why a resistive divider would fail if too much current were drawn but I can’t find that at the moment.

Furthermore, the core-oligosaccharide may be present in different degrees of completion, depending on the class Ra to Re to which the mutant belongs. Products by research area. A digital pin can drive 40mA, up to a total of mA. For output direct connection without problems.

There are several devices in that type of converter that also might work and they only require capacitors for operation, most use. The original post referenced a for a level shifter, go look for a NXP app note AN and read it, might save you some issues re: R-form LPS synthesized by the so-called rough R mutants of gram-negative bacteria lacks the O-specific chain.

I can’t say I’ve understood everything you’ve said in this thread, but I can’t say I haven’t learned anything from it either! By disabling cookies, some features of the site will not work. Not for use in or on humans or animals or for diagnostics.


This mechanism is believed to be true for LPS signaling in general. In my opinion the 74HCT “trick” isn’t really a trick, the voltage levels are right because the parts are designed that way.

LPS from wild type bacteria are always a highly heterogeneous mixtures of S-form LPS molecules containing 1 to over 50 repeating oligosaccharide units and contain a varying proportion of R-form molecules. Linear Tech has one and the web tool to hc40500 it yc4050 So does both National and Maxim, in another place here I posted a long dissertation on switchers and some labor saving tips re: I’ve seen discrete versions of bidirectional level translators consisting of just one FET.

Most 74HCT parts when run on 5V require 3. Didn’t even think about that though, thanks for the suggestion. You touched briefly on “Linear regulator, Don’t even think about bc4050. But I attribute this to lack of coffee – I should have verified my claims: The latter is responsible for the endotoxic activity of the entire molecule.

What do you use? I just stumbled upon this thread again ddatasheet got really embarrassed for not giving proper feedback. By continuing to use our site, you consent to our cookies.

Run HCT parts on 5V and darasheet drive the inputs from 3. If this is not appropriate, could I supply the chip with 3. Given that the LPC, and much other 3. So far I have just ignored this, and most of the time datasheeh works, but I would like to avoid the ‘unsafe’ feeling it gives me.

Basically, I want to never have to worry about replacing a battery as my design is going to be more or less sealed. The layout works 3. IMO and experience in designing low power battery operated solar charged devices. Cart You have no items in your shopping cart.

It is arguable that P type “Fets are available Normal logic-level output current is lower. Gert van der Knokke. As Hendrik has found, it happens that HC parts also work much of the time, since at room temperature their “typical” spec for VIH actually falls below their guaranteed “minimum” spec of 3. As a result magic translators tend to have limited drive or are open-drain with a pull up.

You can look at the data sheets how the logic high voltage daatsheet defined should be either 2 volts, 0. Do not pre-dilute in buffer, e. Under recommended storage conditions, product is stable for at least one year. Then you could buffer the signal up.

This material should be considered hazardous until information to the contrary becomes available. So a 74 HCT is indeed the proper choice.
