Hello,
Regarding to VSEL2 timing on TXS4558, my customer is asking some question.
In their application, VSEL2 is high during VCC is power up.
In this case, VSIM is output 2.95V correctly.
(Please refer bellow diabrames.)
(Question)
1) Do you have a timing of VSEL with respect to VCC?
2)When VSEL is made High, how many more than volts of VCC is needed?
3)Or according to RECOMMENDED OPERATING CONDITIONS, minimum VCC is 1.7V.
So, does VCC need more than 1.7V to enable VSEL?
