SN74LV14A: Fanout

Franz Figueroa32

Part Number: SN74LV14A

Hi E2E,

Good day!

May we know what is the expected fanout for SN74LV14A? We found this document (http://www.ti.com/lit/an/scla007a/scla007a.pdf) which has table 1 for different logic families. However, SN74LV is not indicated.

Looking forward to your response.

Best regards,

Franz

Hi Dylan,

Thank you for your response.

We would like to know the number of fanouts for SN74LV14A. On the document there are some listings for each families. However, SN74LV is not included.

Again, thank you for your support.

Best regards,

Franz

All CMOS families have a fan-out of 1000 or so, due to the high input impedance.

In practice, the fan-out is limited by the capacitive load (not only of the logic gate inputs, but also of the traces and connectors).
