Working Principles

The 74LVT16652ADGG,112 is designed to facilitate bidirectional data transfer between two buses operating at different voltage levels. It utilizes a combination of input/output buffers and control logic to enable seamless communication.

The direction of data flow is controlled by the DIR pin. When DIR is set to a specific logic level, data is transferred from one bus to the other. The OE1 and OE2 pins are used to enable or disable each bus independently.

The IC's internal circuitry ensures that the voltage levels on the inputs and outputs are compatible with both the low-voltage and high-voltage buses. This allows for reliable data transmission without risking damage to the connected devices.
