 		 #183845 - Some of them can handle that.
Responding to: ???'s previous message
If you're working with an MCU that can drive the cable, then that TI transistor array SNGTL2010 or whatever it was, will probably meet your needs. If not, a CPLD has a better chance, I believe, than the typical MCU. Those NMOS FET's won't add prop-delay to the signal path, though, while the CPLD will.

You're the one who'll be doing the work, so you get to decide how you'll do it.

   Suggesting....again...            01/01/70 00:00      
      Alas 5V needed and ribbon cables are a bit "rough"            01/01/70 00:00

         or NXP GTL2010,GTL2000            01/01/70 00:00      
            looks promising            01/01/70 00:00      
            NXP GTL20xx -> NVT20xx            01/01/70 00:00      
         Need to read more to understand them            01/01/70 00:00      
            looks like the cat's miauw            01/01/70 00:00      
   NXP has ....            01/01/70 00:00      
      I2C or SPI just can't get even close to the huge bandwidth            01/01/70 00:00      
         nope, no I²C clocks            01/01/70 00:00      
            extender, not expander            01/01/70 00:00      
   I have been wondering this myself            01/01/70 00:00      
      Supported capacitance seems to be the snag            01/01/70 00:00      
   Differential SPI            01/01/70 00:00      
      Serial -> buffers on adapter boards is a potential solution            01/01/70 00:00      
   Have you considered programmable logic?            01/01/70 00:00      
      I had suggested this as well            01/01/70 00:00      
         Yes ... I remember that ...            01/01/70 00:00      
            Long life            01/01/70 00:00      
               They seem to live a long time ...            01/01/70 00:00      
                  Adapters            01/01/70 00:00      
                     These aren't necessarily so "huge"            01/01/70 00:00      
                        Not huge in size            01/01/70 00:00      
                           Some of them can handle that.            01/01/70 00:00      
                              Yes and no            01/01/70 00:00      
                                 There are ways ...            01/01/70 00:00

                                          Yes, current- and bandwidth-limiting components used            01/01/70 00:00      
                                             you youing whippersnappers, pay attention            01/01/70 00:00      
            pedantry, again            01/01/70 00:00      
               What would YOU suggest?            01/01/70 00:00      
   Here's a thought ...            01/01/70 00:00      
      Probably            01/01/70 00:00      
         I'd sugest you consider older CPLD's            01/01/70 00:00
