spi to parallel

Hello,
I need SPI to parallel converter in one of my application. As ADC has SPI output and I want to use FIFO to store data. But FIFO will not have SPI. Is there any IC which can be used for SPI to parallel converter.

Thanks
 

spi to parallel converter

look at the datasheet for 74HC164.
 

parallel to spi

Try MCP23S17 from Microchip. It is 16-bits IO expender. This chip using SPI bus and it's speed can run up to 10Mhz. You can use 8-bits for data bus and the rest for control bits. Good luck.

Do you want this expander to be an SPI master or an SPI slave? Could you post a rough block diagram? Could you post the part numbers for the ADC and the FIFO?
