Working Principles

The 74AVCH2T45GS,115 is a bi-directional voltage level shifter that allows communication between devices operating at different voltage levels. It automatically senses the direction of data flow based on the DIR pin. When the DIR pin is set to a logic high, data is transmitted from Side A to Side B, and when it is set to a logic low, data is transmitted from Side B to Side A.

The IC operates within a wide supply voltage range of 1.65V to 3.6V, making it compatible with various systems. It features high-speed data transmission up to 400 Mbps, enabling efficient communication between devices. The compact TSSOP-16 package ensures space-saving integration into electronic circuits.
