SN74CBTLV3257: The voltage issue for SN74CBTLV3257

Zhang Liang

Part Number: SN74CBTLV3257

Tool/software:

Hi,

We need to use the SN74CBTLV3257 in our project, and we need set both of the VCC and control input voltage to 3.3V,

can you help to confirm if we need to set the control input voltage less than VCC(example control input voltage is 1.8V and VCC to 3.3V?)

Hello Zhang,

As long as the control input voltage doesn't exceed the voltage supply you will be fine.

You can operate the device with 3.3V in the control input and Vcc.

Thanks,

Nir
