We are moving differential serial data busses into +3.3V single ended into the FPGA
Right now we've selected the AM26LV32E-EP.
This works perfectly for our 10Vpp bus however we have one bus that does 0 to 16V and another that can do 24Vpp. The legacy device a 26LS33 allowed for 30Vpp on the input voltage, the 26LV32 part recommends 14Vpp but does allow up to 28Vpp, however that is absolute max which increases risk of damaging the part.
So two fold question, how big a risk is it to be constantly running the device at 24Vpp, and is there any other solution that can allow for the high differential voltages?
I did try looking at some high speed comparators but the 24Vpp bus runs at a min of 1MHz, so couldn’t find anything quick enough that met the speed required.
