SN54ACT244: In the redundant configuration.

Part Number: SN54ACT244
Other Parts Discussed in Thread: SN54LVCH244A, SN54LVTH244A

Dear Design support team.

It is designed as below.

The redundant IC is in not-supplied. (The primary and redundant channel will be changed in specific condition.)

Is there any problem with this design? In terms of redundant chip(IC) stress or failure due to primary chip operation.

(I don't consider to place the diode.)

Thank you always.
