74VCX164245GX Application Field and Working Principle

The 74VCX164245GX is a logic buffer, driver, receiver, transceiver designed to provide voltage level shifting and/or fan-out capability to Low-Voltage (3.3V) logic families. This device is a member of the Texas Instruments (TI) Common Mode Logic (CML) family, which includes buffers, drivers, receivers, and transceivers.

Application Field

The 74VCX164245GX is intended for use in a variety of applications, including but not limited to systems requiring low voltage translations, fan-out capabilities, and CML logic operations. The device is suitable for a wide range of consumer, industrial, and automotive applications, such as personal computers, digital cameras, and personal in-vehicle infotainment systems.

Working Principle

The 74VCX164245GX is a 2-bit CML buffer that comprises four individual bi-directional buffers. Each buffer has two differential inputs and one differential output. The input logic states are compatible with LVTTL, LVCMOS, SSTL, HSTL, and CML logic families. The device performs voltage level translations between various logic families and provides fan-out capabilities for easier system integration.

The device is powered from a single 3.3V supply and is optimized for use in applications which require speeds up to 1GHz. It works by using internal gain stages to level shift logic families between different voltage levels. These gain stages also provide the additional drive strength needed for fan-out applications.

Conclusion

The 74VCX164245GX is a multi-function device that is ideal for low voltage applications requiring level-shifting and/or fan-out capabilities. It is a versatile and reliable device that is well suited for use in a range of consumer, industrial, and automotive applications.
