Hi Team,

We have a CMOS 3.3V, 125MHz clock output which we need to feed to our PHY which is working on 2.5V. Please suggest us a level translator for this. we need to translate 3.3V to 2.5V.

Hi Mohit,
I would recommend SN74AXC1T45.

Hi Maier,

Could you please suggest us part with EN control, as our clock is unidirectional only. We don't need to control direction.

Hi Mohit,
What do you need the EN pin to do? Are you trying to force the output low or into a high-impedance state?

Hi Emrys Maier,

Yes EN pin should make out Output to the high-impedance state.

In that case, the SN74AUC1G125 or SN74AUC1G126 will do what you want.

Supply the device with 2.5V to get the 2.5V output, and the inputs can be up to 3.6V.
