Other Parts Discussed in Thread: SN74AXC8T245-Q1,
Hello Expert,
Our customer consider to use SN74AXC1T45-Q1 and SN74AXC8T245-Q1 for 1.8V(A port) and 3.3V(B port) application.
In there application, both power supply may not start-up simultaneously so there is the condition that 1.8V is supplied but 3.3V isn't supplied(VCCB=0V).
In this condition, We want to know about Port A's condition if DIR is selected as PortB => PortA.
Then, would you tell me output condition at above situation?
I think, output will be High-Impedance following description in Partial Power Down.
Also, Datasheet said both device have Partial Power Down mode but there isn't any description when it will be released.
Then, would you tell me enter and release voltage of Partial Power Down?
Thank you and best regards,
Kazuki Kuramochi
