about your level translating I2C-bus repeater

Discussion created by Paul Pearson on Apr 25, 2016

I'd like to inquire about your "Level translating I2C-bus repeater", p/n : PCA9517ADP.

 

 

Why is the maximum VOL of Input and Output SDAB and SCLB is 0.6V in your Product data sheet - Table 5, page 10 ?

when the maximum voltage in Std I2C mode device is specified as 0.4V (which means VOL should be less than 0.4V to be LOW level) in the SMBus Specification of the following URL - Table 10, page 57.

  SMBus Specification URL : http://smbus.org/specs/smbus20.pdf

 

This would sound your spec 0.6V max out of the specification.

 

There seems to be my misunderstanding, so could you fill me in on this?

 

Best regards.
