Working Principles

The 74LVTH245MSAX is a bidirectional level shifter/transceiver that translates logic signals between two different voltage levels. It operates by using a combination of CMOS and TTL compatible circuitry to ensure seamless compatibility between different logic families. The device features eight channels, allowing for simultaneous translation of multiple signals.

When the Output Enable (OE#) pin is low, the device is enabled, and the input signals on the A1-A8 pins are translated to the corresponding output signals on the B1-B8 pins. Conversely, when OE# is high, the device is disabled, and the outputs are in a high-impedance state.

The 74LVTH245MSAX operates within a wide supply voltage range of 1.65V to 5.5V, making it suitable for use in various systems. It offers high-speed operation with low propagation delay, ensuring efficient signal transmission.
