Hello,
I'm trying to isolate a SPI peripheral that will often be powered down from the the rest of the SPI bus.
I was thinking about using a TXB0104 or TXB0106. Both VccA and VccB will be +1.8V.
Can I shut off the Voltage to BOTH VccA AND VccB without impacting the SPI Bus? The data sheet talks about EITHER A or B going away and the device going into high impedance. I want to shut both voltages off to save power.
Is there another device family or part that would be more appropriate?
Thank You
Paul
