Part Number: SN74LVC1G3157
Hi!
My customer uses this part 4 times to mux SPI. The SPI signals go from a switch to flash over this mux, in order to disconnect the flash from the programming connector.
Now they missed placing a resistor at the S-Pin., but obviously it works in their first testing.
The thought is still there, that because of the clock frequency, randomly or at start up cases it affects the S-Pin and the Switch can't read from the flash.
How high is the probability for this?
Is there a Weak-pull down internally?
Kind regards,
Marion
