Hi,

Iam using SN74LVC1T45 1-Bit level translator for SPI signals for level translating from 5V to 3.3V . I want to operate SPI over 10-25Mhz ,whether any issue will come???

KINDLY PROVIDE THE MAXIMUM DATA RATE AT THIS TRANSLATION.

Hi Shiju,

I see no issues for the SN74LVC1t45 to support 25Mhz for 5V <>3.3V translation. This device can support up to 400Mbps (200Mhz).
Are you using 4 of the LVC1T45 devices here for the SPI translation or using LVC2T45 and LVC1T45 devices?

Thank You for reply.

I am using 4 Nos of single bit SN74LVC1T4 in my board,Due to some PCB Placement Limitations,Whether any issues will be there due to the usage of 4 single bit SN74LVC1T4 for SPI.

Shiju,

understood. There is no issue with using 4 of the devices. I had given my suggestion for your consideration.
