Part Number: SN74LVC1T45
Other Parts Discussed in Thread: SN74LVC2T45,

Hi team,

Is there a power up sequence for the SN74LVC1T45?

I found guidance on the power-up considerations for the SN74LVC1T45-EP as well as for the SN74LVC2T45.

Please clarify the difference here.

Thanks!

Hi Go,

The power-up recommendations are for guidance only and not a requirement. I would recommend following the SN74LVC2T45 power sequencing for LVC1T45 as well.
The IOs being at a known state (gnd through weak pulldown) is also advised.

Thank you. Can this be updated in the datasheet?
