Hi Team,
My customer is evaluating the SN74CBTLV3257 on their board, and they measured signal collision waveform at switching. Could you review their measurement waveform below and let me have your answers?
SN74CBTLV3257 Waveform at signal collision 20200603.xlsx
Q1) When switching the S pin, is it possible that both the SW of the B1 pin and the SW of the B2 pin are both turned ON at the same time?
Q2) When switching the S pin, is there something like dead time provided for the B1 and B2 pins so that both do not turn on?
Q3) Regarding this phenomenon, is it possible to prevent signal collision by controlling the /OE pin as shown below?
'/OE=Low --> Switch /OE pin to High --> Wait 1ms --> Switch S pin --> Wait 1ms --> Switch /OE to Low
Q4) Is there a measure other than the method described in Q3)?
Thank you.
Best Regards,
Koshi Ninomiya
