The MC74LVXC3245DTG is a low-voltage, high-speed universal multiplexer/demultiplexer logic translator. The logic module is designed to help provide reliable signal conversion between low-voltage logic families, such as CMOS and BiCMOS. It is suitable for applications including low-voltage busses and switching between AV/C and digital video interface (DVI) formats. This device is available in both octal and dual modes, providing signal conversion within the same bus or over two separate busses.

Application Field Of The MC74LVXC3245DTG

The MC74LVXC3245DTG is ideal for a wide range of applications. It is most commonly used as a logic translator between different logic families operating at either 3.3V or 5V power supplies. It can interface between Standard CMOS and BiCMOS, as well as between other logic families including EC, CEC, DTL, TTL, TTLQ, FCT and FET logic. The MC74LVXC3245DTG can also be used as a multiplexer between DVI and AV/C interfaces, and as a level translator to adapt signals for different speed domains. It is also suitable for use in communications systems, networking systems, and audio/video equipment.

Working Principle Of The MC74LVXC3245DTG

The MC74LVXC3245DTG is a low-voltage translator and level shifter that uses two independent voltage rails. When the device operates in octal mode, the voltage rails are provided by the two separate busses. When the device operates in dual mode, the voltage rails are provided by the same bus. In either configuration, the device automatically selects the appropriate voltage rail according to the logic family of the data being transferred. The device also provides high-speed signal translation, facilitating the conversion and transmission of data between different logic families.

The MC74LVXC3245DTG also provides bidirectional signal translation and fan-out control. In bidirectional mode, the device can run from either the input or the output side, converting data from one logic family to the other. In fan-out mode, the device can provide a reduced signal edge rate in the output to allow for multiple outputs. This feature eliminates the need for a separate buffer or dedicated output driver.

The result is a compact, low-cost device that is simple to use and offers robust signal conversion between different logic families. Its low voltage operation and high-speed operation make it an ideal choice for applications requiring reliable signal translation between different logic families.
