The reason amount converter you have pointed out keeps two bidirectional, open-drain stations by FETs, and two one-way amount move channels (HIGH-In and LOW-out) by resisters performing current divider. Bidirectional open-drain levels shifters tend to be (by picking proper FETs) suitable for I2C coach, it enjoys set tall- and Low-voltage side. Buffer-gate means bidirectional amount shifters like TX010x depending ones posses two edges and any area from it can be allotted to significant (or Low) current area, though traces pulled-up may mistake the chip as supersat stated earlier rather than appropriate for I2C.
No slew. No stress. I’m really pleased to see you men produced this a breakout board. One-word of caution, though. The VCC Isolation feature (which places the pins in a HighZ condition) operates during startup only when your tie OE to ground via a pulldown. It does not matter which rail influence up very first, but through to the VCCa train is actually stimulated OE will still be conducted lowest, maintaining the pins HighZ. Hence – don’t forget to hook OE to GND with a weak 
pulldown (10-50k), and then leave the solder jumper linked.
No promises, but from rapid glance it seems like Texas Instruments CD4504 might suit you perfectly. It really hinges on what you are trying to carry out with it. I2C? SPI? Present from 5-20V. Tie CHOOSE to GND and you will has your self a A-B CMOS translator.
My personnel is consistently constructing prototypes which include incorporating numerous off the rack eval panels with this agencies innovation as well as other solitary board microcontrollers, thereby seemingly always looking for shifting degrees between products. After debugging and evaluating the prototypes, we commonly bring the TXB010X category of level shifters (typically in an inferior plan and for sale in 1,2,4,6, or 8 little) to our custom boards which will help protect consistency for debugging.
This panel is a simple breakout panel getting the indicators to 0.1″ header gaps while simplifying the OE reference to a solder jumper to VCCA, reducing further soldering efforts should you merely want this product always-on. In circumstances where power is crucial or it is good for come like a bus might disconnected, the OE pin could be set large by a GPIO to shut down the product and the outputs goes to a top impedance condition.
Since TXB0104 is mainly intended for push-pull signals rather than open-drain it truly does work very well for UART and SPI shuttle software, whereas for open-drain signals instance I2C, the BOB-12009 is actually a better alternative (which I also typically buy in bulk and stock within our laboratory).
Good-for SPI
I tried amount shifting an ADXL362 breakout panel with resistors and simply have trash out of the panel. However bought the TXB0104 slapped some header pins on it and installed onto my personal breadboard and is working within a few minutes. I found myself in a position to run my personal SPI_CLOCK_DIV all the way doing 2 on a 16MHz Arduino acquire information from ADXL362. Since I have ‘m going to integrate the particular TXB0104 processor chip into a custom board i prefer the concept of obtaining the four outlines dealt with with the minimum feet printing and parts compared to making use of individual BSS138s.
level shifter
while it might-be good, I got confused with stage shifter that may very well benefit I2C coach. The data sheet on the TI tool indicates that this panel cannot be used in I2C coach level shifting.
Useful product
It is a convenient and low-cost way to a common challenge. One problem we went into–and its a problem with the IC, perhaps not with SparkFun’s breakout board–is your IC will oscillate in the event the load on any production is actually big. If you find that is the case, create a buffer IC downstream of this result.
