→ I can help identify the real component and find its exact datasheet.

Days turned into weeks, and Alex was about to give up on his search. But then, he received an anonymous message from an individual who claimed to have worked on the Highway 09 IC project. The message read:

Given the 40V input rating, you can add a transient voltage suppressor (TVS) like an SMBJ36A at the input to clamp load dump spikes. A series Schottky diode prevents reverse battery.

With the new information, Alex began to share his findings with the electronics community. The Highway 09 IC datasheet, once a mystery, was now out in the open. Although the IC itself may never be produced, its legacy lived on.
