Ken, have you successfully used this chip as you describe? Thanks Graham Ken Pergola wrote: Hi Graham, The FT245xM's bus is *only active* when RD# is asserted and is tristated otherwise. When you want to share the bus, you must make sure RD# is not asserted.

Has anyone had success using the FT245BM? I am trying to use it in a prototype design, but am wanting to share the data bus with other peripherals (e.g. LCD). I have the device self powered as per the user guide. The problem I can see is that as soon as the USB cable is plugged in, the chip will come out of reset and its data bus pins will not be tristated, and I won't be able to share the data bus with any other device.
