Other Parts Discussed in Thread: SN74CBT16390

Hi Team,

My customer would like to use the following input signal.

Can SN74CBT16390 let this input signal go through?

We can’t judge it because input frequency isn’t mentioned in datasheet.

[Input signal]

-Voltage = 1.8V

-frequency = 54MHz Clock

Regards,

The frequency is no issue but since the CBT16390 is an Nchannel it will have 1V drop at output from VCC.

Vcc will need to be greater than 2.8V.

Hi Chris-san,

Thank you for your prompt reply.

Vcc of SN74CBT16390 is 5.0V.

So, I understood that my customer can use SN74CBT16390.

And, I have one more question.

Could you please let me know a value of the max input frequency?

Regards,

Kanemaru
