2:1 multiplexer for high-speed signal routing
The Microchip SY58018UMG-TR is a single 2:1 multiplexer from the Precision Edge® family, designed to route one of two input signals to a common output. It operates from either a 2.375V–2.625V or a 3V–3.6V single supply rail, making it compatible with both 2.5V and 3.3V logic families commonly used in telecom and data-communications line cards.
Supply voltage — which rail to pick
The dual supply range covers 2.5V and 3.3V nominal rails. The 3V–3.6V window matches a 3.3V core supply, and the 2.375V–2.625V range matches a 2.5V rail.
Temperature grade and deployment
It is not rated for automotive under-hood or engine-bay environments — those would need an AEC-Q100 qualified variant if one exists in the family.
