Working Principles

The SN64BCT757N is a bidirectional logic level translator that allows seamless communication between two voltage domains. It utilizes a combination of MOSFETs and CMOS technology to achieve non-inverting translation. The DIR pin controls the direction of translation, while the OE pin enables or disables the outputs.

When the DIR pin is set to logic low, the A ports are connected to the B ports, allowing signals to pass from one voltage domain to another. Conversely, when the DIR pin is set to logic high, the B ports are connected to the A ports, enabling bidirectional translation in the opposite direction.

The SN64BCT757N operates within a wide supply voltage range, making it compatible with various systems. It also features a high-speed data rate of up to 100 Mbps, ensuring efficient signal transmission.
