Can I have a switching waveform as like this?
I want to confirm a good low noise signal transfer/receive device.

At 3.3 V, the drive strength of the 2N7001T is 12 mA, which is similar to that of the AC244.
Section 8.3.2 of the datasheet says:
The drive capability of this device may create fast edges into light loads, so routing and load conditions should be considered to prevent ringing.
To reduce the drive strength, you can add a series resistor to the output.
Shreyas,
If actual waveform of 2N7001T is like AC244 as Clemens said, it isn't good even add a series resistor from our experience.
Do you have any other device for similar function with waveform like LV244A?
Shreyas,
Thanks.
I need Up and Down Translation across 1.8V and 3.3V.
And I hope included ESD protection.

Does "up and down" imply that the signal line is bidirectional? Or is there more than one line? (In the latter case, how many, in which direction?)
The only device with higher than usual ESD protection is the TXS0102, but it has strong edge accelerators.
There is no single two-channel device that has one channel in each direction.
I recommend a translator with weak output drivers (e.g., SN74AUP1T17) for uptranslation, and a buffer with weak output drivers and overvoltage-tolerant input (e.g., SN74AHC1G125) for downtranslation.
