Working Principles

The SN74LVC823ADWR is a logic level translator that facilitates communication between devices operating at different voltage levels. It uses a bidirectional voltage translation technique to convert signals from one voltage domain to another. The direction of translation is controlled by the DIR pin, which determines whether the data flows from Port A to Port B or vice versa.

When the DIR pin is set to a logic high, the translation occurs from Port A to Port B. Conversely, when the DIR pin is set to a logic low, the translation occurs from Port B to Port A. The OE pin enables or disables the output ports, allowing control over data transmission.

The IC operates on a wide supply voltage range and utilizes low voltage CMOS technology, ensuring compatibility with various systems while minimizing power consumption. The high-speed operation of the SN74LVC823ADWR enables efficient data transfer between different voltage domains.
