SN74LVC157A Signal Rate

Other Parts Discussed in Thread: SN74LVC157A

Hi team,

What's the max signal rate of SN74LVC157A in 3.3 or 1.8V application?

Customer wants to evaluate whether it could be used in a 10MHz SPI bus (1.8V/3.3V).

Thank you!

Hi Luke!

If there isn't a value given you can have a look at the propagation delay to estimate the maximum frequency. Here is an example for another device:

Dennis,
Thank you. Then SN74LVC157A seems couldn't support 10MHz SPI. Do you have any other parts that could be used?
