Working Principles

The 74LVC16245APVG operates by receiving input signals on the A-side and transmitting them to the B-side, or vice versa, depending on the direction control signal (DIR). The output enable signal (OE) controls the tri-state outputs, allowing the IC to be effectively disconnected from the bus when not in use. The bidirectional level shifting is achieved through a combination of internal circuitry, which ensures proper voltage translation between different logic levels.
