TS5A23157-Q1: please double check the application scenarios

Part Number: TS5A23157-Q1
Other Parts Discussed in Thread: SN3257-Q1

Can I use in this scene: I use 1.8V for V+, but 3.3V for IN1 and IN2. Can TS5A23157-Q1 work well?

No, the absolute maximum ratings forbid this.

The SN3257-Q1 supports input voltages beyond the supply.

Hello,

I agree with Clemens answer and to understand what to do with the unused pins in your application please look at this FAQ.

Hi:

Thanks for update.

Can I use in this scene: the V+ and IN1/IN2 are both 3.3V, but the high voltage of NC/NC/COM are 1.8V. Can TS5A23157-Q1 work well?
