Level Shifting between 1.5V and 3.3V

how many bits?

Hy Chris,

I need to level shift 6 "bits", or signals. Clock, Chip-Select and 4 x Data (bi-directional)

I am looking forward to your answer.

Niels

this is a tough one. We have a part coming out fairly soon that would work.  When do you need parts?

It will be the LSF0108.

It will be the same as this part but have 8 bits.

LSF0102

Take a look and see if this might work.

Hello Chris,
hope you had a nice weekend.

Thank's for pointing out this part. It sound very nice, and reminds me of the PCA9306.
I had a look at the PCA9306 data sheet, and fond that it is very similar to the LSF0102.

Would it be possible to use the PCA9306 also?
What is the difference between LSF0102 and PCA9306?

I am looking forward to your answer.

Regards,
Niels

Chris,
sorry for not answering one of your questions:

I need the parts in May 2014. That's one reason why I asked you about the PCA9306.

Chris,

I just did a few IBIS simulations and recognized that SPI Flash devices are not capable of driving several Milli-Amps against a strong Pullup resistor.

In the data sheet of SPI-Flashes, you find ony Vout high and low values for 100µA output current. That's all.

I fear that it is not possible to use a solution that relies on pullups.

OK,

thank you.
