DS25BR150: DS25BR110

Other Parts Discussed in Thread: DS25BR110

Hi,

Good Day. 

I actually use DS25BR150, but I would like to use DS25BR110. On my board, pins 1 and 4 are NC and I would like to know if it is a problem with the DS25BR110 because for this PN indicates pins 1 and 4 in GND or VCC.

And I would like to know if I leave these pins 1 and 4 NC what is the assumed state?

Please advise. Thank you very much.

Best Regards,

Ray Vincent

    Greetings,

    On DS25BR110 pins 1 & 4 are EQ0 and EQ1 - input equalization control. These two pins are LVCOMS and need to be driven either high or low. We should not leave these pins NC(No Connect) since floating LVCMOS inputs could be prone to noise and cross talk.
