IDT74FCT164245TPVG8

The IDT74FCT164245TPVG8 from Renesas Electronics is a 16-bit bidirectional voltage-level translator belonging to the 74FCT164245T family, engineered to interface 3.3 V and 5 V logic domains in high-speed digital systems. Fabricated in low-capacitance Fast CMOS technology, the device incorporates non-inverting 3-state outputs, TTL-compatible inputs on both ports, and independent output-enable and direction control for each 8-bit bank. This organization enables full 16-bit translation with minimal propagation delay and low dynamic power consumption, while the bus-hold feature on data inputs eliminates the need for external pull-up resistors. The SSOP package provides a compact footprint suitable for dense board layouts without sacrificing signal integrity.

Typical deployments include data and address bus bridging in industrial automation controllers, mixed-voltage backplane interfaces in aerospace and defence avionics, communication line cards, and test-and-measurement instrumentation where legacy 5 V peripherals must connect to modern 3.3 V FPGAs or microcontrollers. Procurement engineers should note that the PVG8 suffix designates an SSOP package with lead-free, RoHS-compliant plating and tape-and-reel orientation for automated assembly. As a mature logic product from the former IDT portfolio now supported by Renesas, the series benefits from long-term supply continuity, yet lead times can be constrained by legacy fab allocations; verifying current lifecycle status and alternative source availability is advisable for new production programs. The part is rated for commercial and industrial temperature ranges, and while no military suffix is present, extended-reliability screening may be available through Renesas upon request for high-reliability programs.
