ALM2402-Q1: if there is internal clamping diode between VIN and V+

Part Number: ALM2402-Q1
Other Parts Discussed in Thread: LM2904-Q1, LM2903B-Q1, LM2904, LM2903B, LM2904B-Q1

Hello experts,

Hope you are doing well.

I would like to ask if the LM2904-q1 op amp has an internal clamping diode.
In customer's test, when the amp is asleep, the V+ is not powered, but the input of the op amp is high.
In the case that V+ is not powered (with decoupling capacitor connected to V+), will there be a path from VIN to V+?
If there is a pathway, can a diode be added with V+ to block the pathway to battery as below?

Besides, I noted there is clamp diode in LM2903B-Q1, it seems LM2904 is different in block diagram, can you help with it? Thanks.
