Altera Cyclone II to Mc68000

[majsta]

Hi all, my idea is to use Cyclone II to replace Mc68000 on Amiga board, but there is some problems. Cyclone dont have 5V tolerance so i need to solve that. I read on this forum about level shifters, quickswiches with zero delay, and buffer transceivers.
I read about quickswich QS3861, and level shifter(transceiver) 74lvc4245,SN74LVTH16245A
1. What is the difference between Level shifter and quickswich and buffer transceiver ?
2. In buffer transceiver what does mean by Type buffer: Non Inverting or Inverting
3. Do i need to use bi-directional device?
3. On the devices nuber of bits stands for number of inputs/outputs ?

There is a lot of devices that i simply dont know what to do. I was thinking about 74ac11244dw, idtqs3384qg.

And beacuse i use some cyclone Ii dev board, and i want to make cables to connect that board to MC68K socket, do i have to use some Amplifiers like LT6200CS8 because dev board is too far away from mc68K socket.

There is something wrong with quickswich devices. As I know MC68000 cant
support 3.3V (some versions can but mine just cant). When i use quickswich
any type i only get 5V to 3.3V translation and no vice versa. I need to use
dual voltage level translator with auto sensing. Only parts that I can
found with this is txs0108e even sn74lvc8t245 have direction control.
For last two days I m reading about Pericom articles and those articles are
just like IDT have for quickswich part. Devices are working from higher to
lower and I m thinking that I just cant use those devices. For some devices
who work with 5V can drive lower voltage levels that is ok but on my
situation is not. For example PI5CX and PI3CX series are only related to 5V
to 3.3V translation no bidirectional and then i need to use bus enable
input like on most devices. From A to B bus or from B to A bus, that is not
practical. Also some Pericom devices PI74LVC4245 who have two voltage on
each bus side but no auto sensing again I need to set direction sides. I
just dont know, as much i m reading only thing is txs0108e that I m using
on design right now. Also using Pericom or IDT devices we can use pull up
resistor connected to higher power source. I just dont know....
