The 74LVXC3245TTR is a logic-level translator belonging to a family of wire-to-wire translations of logic signals between different logic voltages, specifically a 0.4V to 2.4V range for the A-inputs and the B-outputs. It is the most commonly used type in the 74LVX family, targeting applications including those that require short-distance signaling between various serial buses. Moreover, this device is designed to effectively transfer signals between low voltage, low power, CPD-protected devices such as laptops, tablets, phones, and other mobile gadgets, and devices that run at logic levels other than 0.4V to 2.4V.

The A-inputs of the 74LVXC3245TTR do not draw any current in the absence of a logic input. This allows the device to be used in systems that have power-saving features, since the A-inputs can easily be operated at low supply voltages. The B-outputs similarly have the capability to draw no current in the absence of a logic signal, meaning that the output can be safely pulled low to GPIO voltage levels.

The 74LVXC3245TTR also includes extensibility pins to allow for addressing, such as for larger multiplexer applications in which address termination is mandatory. Also, it has a data retention mode, allowing for the storage of data during times of power interruption. Like other members of the 74LVX family, the 74LVXC3245TTR has a wide hot-insertion voltage range of 4.5V to 3.4V.

In terms of working principle, the 74LVXC3245TTR performs level shifting through the use of transistor channels and PMOS devices that allow the circuits to selectively draw current on the A-inputs and the B-outputs. It also has a driver enable circuit that limits the current that the device can draw, while simultaneously providing negative feedback to ensure that the voltage is within accepted limits. The level shifting of the device is powered by a power block of 4.5V to 3.4V.

The 74LVXC3245TTR is always a one-to-one device, and it is generally used in applications that require low power operations and easy-to-use configurations. It is also typically utilized in applications ranging from static data collection to audio signal transmission or transfer. In short, the device’s primary purpose is to translate 0.4V to 2.4V logic levels to other voltages, while also providing extensibility features to facilitate larger multiplexer applications.

In conclusion, the 74LVXC3245TTR is a logic-level translator belonging to the 74LVX family that is designed to effectively transfer signals between low voltage, low power, CPD-protected devices. It has a wide hot-insertion voltage range of 4.5V to 3.4V and is generally used in applications that require low power operations and easy-to-use configurations.The device performs level shifting through the use of transistor channels and PMOS devices and has a driver enable circuit that limits the current that it can draw, while also providing negative feedback to ensure that the voltage is within accepted limits. This device is an invaluable tool for transferring logic levels between 0.4V to 2.4V and is typically used for static data collection, audio signal transmission, and transfer.
