SN74ALVC164245DLR

The Texas Instruments SN74ALVC164245DLR is a 16-bit dual-supply bus transceiver from the ALVC logic family, designed for high-speed voltage-level translation between mixed-voltage digital systems. This device features two independent supply rails (VCCA and VCCB), allowing each port to operate at a different voltage—typically 2.5 V or 3.3 V on one side and 3.3 V or 5 V on the other—providing a seamless interface between low-voltage processors and higher-voltage peripherals. The non-inverting transceiver includes direction control and output-enable pins, and its ALVC architecture delivers fast propagation delays with low static and dynamic power consumption. The 48-pin SSOP package (DL suffix) offers a compact surface-mount footprint suitable for dense board layouts while maintaining excellent signal integrity.

Typical applications include industrial automation controllers, embedded computing platforms, aerospace data-acquisition systems, and telecommunications infrastructure where reliable mixed-logic interfacing is required. It serves as a bus buffer, level shifter, or data-path isolator between FPGAs, microcontrollers, memory, and I/O devices operating at dissimilar voltage levels. For procurement engineering, this active Texas Instruments component benefits from a stable product lifecycle and broad distribution, minimizing obsolescence risk in long-life programs. The part is rated for industrial temperature operation, making it suitable for high-reliability environments outside of full military qualification. Standard tape-and-reel packaging supports automated assembly, and the established supply base ensures repeatable sourcing for prototyping and production quantities.
