SN64BCT25244 3.3V replacement

Other Parts Discussed in Thread: SN74LVC541A, SN74LVTH240, SN64BCT25244

Hi,

I am using the mentionned IC to drive 50-ohm lines. To achieve a 2ns rise time, I'm connecting 2 inputs/outputs in //.

That work perfectly, but requires 5V power supply. I'm looking for another solution with 3.3V. Any recommandation?

Cheers,

Jerome

Hi Jerome,

Have you looked at the SN74LVC541A?

Hi,

Thanks for your answer.

SN74LVC541A was my 1st idea but the output current is much lower: +/- 24 mA instead -80/188 mA. So my rising time would be increased...

Cheers,

Jerome

Hi Jerome,

There is also the SN74LVTH240. I don't know if we have anything with higher current drive than that at 3.3 V.

Hi,

I'm going to keep the SN64BCT25244 as nothing in 3.3V seems to meet my requirements.

Thanks again.

Jerome
