SN74LV125A: Output parasitic capacitance

Shuji Ishiwata

Part Number: SN74LV125A

Hi All,

Please tell me the capacitance (parasitic capacitance) of each output terminal of SN74LV125APWR and SN74LV244APWR.

Best Regards,
Ishiwata

Hi Ishiwata-san,

We don't have data for this measurement. You can probably expect between 3-5pF.

Hello Malcolm-san,

Thank you for your answer.
I have an additional question. Please tell me the output rise and fall times (Tr/Tf) of both products.

Best Regards,
Ishiwata

Hi Ishiwata-san,

This depends on the output load and operating voltage. Please see here on how to calculate the rise and fall times:

Hello Malcolm-san,

Thank you for your answer.

I have an additional question.
Is the parasitic capacitance of the output of SN74LVC also around 3-5pF?

Yes, I would expect so.

Best,

Malcolm
