Hi Team, we would like to confirm if these devices can function on a vacuum environment. The customer intends to use it on Vehicle Tracking System.

Thank you very much.

Normal plastic packages probably have a high rate of outgassing. In any case, it's not tested.

The SN54HC273-SP and UC1637-SP are guaranteed to work in vacuum; see the Space Guide.
