My customer VNL has used a "SN74AVC1T45DBVR" in one of the design.
So as per its datasheet, Power-Up sequence for VCCA & VCCB to be maintained as follows:
1. Connect gnd before any supply is applied
2 power up VccA
3.Vccb can be ramped up along with or after Vcca
And the operating voltage of VCCA & VCCB is 1.2V-3.6V.
Is point 3 to be followed for whole voltage range OR to be followed till the device get entered into operating range?
Kindly also comment on the attached waveform for power-up sequencing of VCCA, VCCB.
Also i have attached the powering up sequence
please share your views on the same
