e2e,

I'm looking for a 5:10 signal switch/mux for a SPI interface.  Would a device similar to IDTQS3VH257 be appropriate?

Thank you,

Adam

    Hello Adam,

    The direct replacement for the IDTQS3VH257 shown in the schematic below is SN74CB3Q3257.  I found this replacement using the TI.com cross reference tool.

    TI currently doesn’t have an 5-channel switches.  The closest match that TI.com search tool provides are 4-channel 2:1 like the IDTQS3VH257 or SN74CB3Q3257 or 6-channel 2:1 devices like the TS3A27518E.   I have provided a list of my search on TI.com below which also includes devices with powered off protection which means the signal path is Hi-Z when there is no power to the switch Vcc= 0V.  I think this feature is desired in server applications.    

    Thank you,

    Louie
