Description:
This 8-bit noninverting translator uses two separate configurable power-supply rails.
The A port is designed to track VCCA. VCCA accepts any supply voltage from 3.6 V.
The B port is designed to track VCCB. VCCB accepts any supply voltage from 5.5 V.
This allows for low-voltage bidirectional translation between any of the 2.5-V, 3.3-V, and 5-V voltage nodes. When the output-enable (OE) input is low, all outputs are placed in the high-impedance state.
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

Level shifter works as expected level shift 3.3 to 5v. on my orange pi 2w zero (allwinner h618 soc) the chip produced a nice 56Mhz oscillation from 3.2v to 2.0v with any input signal on port A. I had to add an RC filter on port B output (50-75ohm, 500pf - 1nf). If I had a sufficiently low value inductor I would have used an LC filter to preserve rise and fall times. Anyway, I ended up switching to a Schmidt trigger (sn74lvc-xxx) powered at 5v and had incredibly sharp transitions, no need for any filtering, just nice clean signal.TLDR: use a schmidt trigger for signals over ~400Kbps (YMMV)

Utilizados para varias PCB entre pines de arduino y señales de sensores de bajo nivel. Funcionan muy bien. No lo he probado a grandes frecuencias pero para buses estándar van bien.

I didn't realize that this IC (TXS0108) is not the same as the TXB0108 which I have been using for years. I use the TXB0108 to convert UART signals between a 3.5V microcontroller and a 5V device. This PCB with the TXS0108 apparently works differently and I think it requires other components because all my connections were find but data was not going through. For the price of the TXB0108 dev board, I didn't wast time goign through the datasheets of the TXS0108 to figure what was wrong, I just ordered the TXB0108 from another website.

Chaque composant possède 2 rangées de 10 broches.Après avoir reçu la commande, j'ai regardé le descriptif de l'article sur Amazonet celui-ci précise que l'article est livré avec 2 connecteurs de 8 brocheset en fin de compte, on reçoit 2 connecteurs de 7 broches.Remarquez 8, c'était déjà perdu.

Using to convert MIDI signals from 3.3 to 5 v and back. Also good for i2c
