I am looking for a quad 2:1 multiplexer to select one of two SPI signals from the input.
ADG3257 seems to be a good candidate.
Page 6/12 of its datasheet (Rev.E) shows the pin configuration and function descriptions.
By the way, I cannot figure out how to configure port B (1B1, 1B2, 2B1, 2B2, 3B2, 3B1, 4B2, 4B1) as an input and port A (1A, 2A, 3A, 4A) as an output.
Can you please give me a hand?
