IDT74FCT164245TPVG

The IDT74FCT164245TPVG from Renesas Electronics is a 16-bit bidirectional voltage-level translator integrated circuit that provides a high-speed interface between 3.3 V and 5 V logic domains. Fabricated in a Fast CMOS (FCT) process, the device offers non-inverting translation with low propagation delay and reduced power dissipation, making it suitable for mixed-voltage systems that demand signal integrity. Independent direction control on each byte permits flexible bidirectional data flow without external glue logic, while the SSOP package delivers a compact surface-mount footprint for high-density board layouts in industrial and embedded designs.

Typical applications span bus bridging between low-voltage processors and legacy 5 V peripherals, data-path buffering in backplanes, and interface translation in industrial automation, test instrumentation, and avionics equipment. The device's fast switching characteristics support reliable operation in mission-critical environments where timing margins are tight. From a procurement perspective, this lead-free (RoHS-compliant) component carries an active lifecycle status under Renesas, reducing immediate obsolescence risk for new designs. Engineers specifying the part for aerospace, defense, or other high-reliability applications should verify the exact operating temperature grade and examine whether supplementary screening or alternative military-suffix variants are required, as the standard industrial-grade TPVG suffix may not satisfy full mil/aero qualification requirements without additional compliance measures.
