Part Number: SN54LVTH244A-SP Are SN54LVTH244A-SP inputs cold sparable? That is .. is there a high side ESD clamp diode? If power is OFF on this device .. and the input is driven from a powered ON device .. will this high side ESD clamp diode form a sneak…
A current will flow through the second buffer's outputs into the not-supplied V CC .
You need buffers with the I off feature. But there is no such 5 V device; the SN54LVCH244A or SN54LVTH244A run only with a 3.3 V supply.
Part Number: SN54LVTH244A-SP Other Parts Discussed in Thread: SN54LVTH244A , SN74LVTH244A Hi Sir/Mdm,
The datasheet for SN54LVTH244A does not indicate any value for IOFF. Is it because it is not tested or there is no such parameter?

Part Number: SN54LVTH244A-SP abs max rating lists "current into any output in the high state, Io" only for Vo > Vcc (Note 2). Is there abs max rating for high state current when Vo < Vcc?
An isolator like the ISO7041-Q1 makes sense only for galvanic isolation.
The SN3257-Q1 would be able to disconnect the signals. Alternatively, use any buffer with Ioff protection, e.g., SN74LV125A-Q1 or SN54LVTH244A-SP.
Other Parts Discussed in Thread: SN54LVCH244A , SN54LVC541A , SN54LVTH244A Hello,
We have read through the SNJ54AC244W datasheet and this document on CMOS devices http://www.ti.com/lit/an/scba004c/scba004c.pdf , but I'm having trouble finding the following…
