| Feb 21, 2016 at 18:51 | comment | added | cocco | lately i tested various logic level shifters... i don't have a oscilloscope but i needed a very fast transmission and most of those mosfet/transistor circuits or other ic's could not handle the speed. the chips that worked properly are the 74HC125 / 74HC126 & 74LVC245 & TXB0108 | |

| Jan 28, 2014 at 9:30 | comment | added | alexan_e | For example when you want to connect the 5v arduino to a 3v SPI flash memory or a SD card or I2C device then the signals between the two devices transfer at some rate depending on the clock rate you set for the peripheral, the translator should be able to keep up with that rate of change. On the other hand is you are just interested to transfer an enable line (more like static signal) then frequency doesn't make much sense. | |

| Jan 28, 2014 at 9:15 | comment | added | 3bdalla | I'm not sure that I got your point, I haven't dealt with frequencies before, my purpose is for simple electronics :| | |
| Jan 28, 2014 at 9:07 | comment | added | alexan_e | What will be he frequency of the signal you are going to transfer, it can be 10KHz or 100KHz or 1MHz... | |
| Jan 28, 2014 at 8:59 | comment | added | 3bdalla | For example assume I want to connect 5V device to a 3.3V arduino. I couldn't figure out where to connect the 5V output and the 3.3V input. And what about output a 3.3V from an arduino for example to a 5V device ? What do you mean by frequency range ? | |
| Jan 28, 2014 at 8:51 | comment | added | alexan_e | What is the intended frequency range? | |
| Jan 28, 2014 at 8:49 | comment | added | Dzarda | You'd better provide info about why or how you don't understand how they work or how to interface with them... | |
