For an SPI application:
I am trying to find a bus switch to isolate the connection the SPI bus connection between PCIe switch and SPI flash. And Dediprog programmer and same SPI flash
PCIe switch .....Bus Switch....SPI Flash
Header for SPI programmer...Bus switch...Same SPI Flash
Only one path will be ON at a time
An Octal (With 2 enables for each quad path) or two quad devices will work for my application. But I am not able to find a device that works at 1.8V. Is it okay to tie Vcc to 3.3V and run the I/O on both sides with 1.8V logic?
Can you recommend me an IC?
