Working Principles

The CY74FCT823CTQCTG4 is a logic level translator IC designed to facilitate communication between different voltage domains. It operates by receiving input signals from one voltage domain (A port) and translating them to the corresponding voltage levels of another domain (B port), and vice versa. The bidirectional data flow allows for seamless communication between the two domains.

The IC incorporates output enable control, which allows users to selectively enable or disable the translation process for each port. This feature provides flexibility in managing data flow and conserving power when translation is not required.
