Hello,

I am facing issue in converting fully differential converter.

I have differential TTL which I need to fanout by factor of 3 or 4.

But the i do not want output termination resistor on differential output.

Could you please suggest.

If I use single ended op-amp

Thanks,

muni

Hello Muni,
Are you looking for a TTL differential mux or an analog mux to work with the THS4551 differential input op amp?
Please explain your requirement in more detail.

Hello Ed,

I am looking for TTL differential buffer which has to just support many ICs.
I have complementary signal which goes from 0->5V and 5V->0V

I need to duplicate the same signal at output for three channels. If I directly give there will be loading effect.
So I am looking for a buffer at the same time, It should not introduce the skew between the differential line which will create a balance error.

Could you please suggest any solution with op-amp

Thanks,
Muni

Hi Muni,
From your schematic, it looks like your signals are all 0V to 5V (nothing exotic like -5V to 0V). If this is correct, you can use a standard 5V buffer for the job like SN74HC244.
