IDT54FCT162244ATEB

The IDT54FCT162244ATEB is a Renesas Electronics (formerly IDT) 16-bit non-inverting buffer/line driver housed in a hermetic ceramic flat pack (CFP), built for high-reliability environments where extended temperature operation and physical robustness are essential. This device belongs to the FCT family of fast CMOS logic, combining TTL-compatible inputs with full 5 V operation; typical propagation delays remain well under 5 ns while the balanced output drive limits simultaneous switching noise. All 16 channels feature independent 3-state controls, enabling seamless integration into bidirectional data paths and heavily loaded backplanes. The CFP package provides a true hermetic seal, ensuring long-term stability in humid, corrosive, or high-altitude conditions that plastic packages cannot sustain.

Typical deployment scenarios include military avionics bus buffering, radar signal distribution, ruggedized embedded computing, and secure communication infrastructure where deterministic timing and low skew are critical. The “54” prefix designates the full military temperature range of –55 °C to +125 °C, making the part suitable for defense and aerospace systems that must meet derating guidelines and long mission life requirements. Procurement teams should note that this is a specialized ceramic-packaged logic device, and while the FCT family remains supported, older speed‑grade and package combinations can face constrained availability or eventual obsolescence; verifying current lifecycle status and maintaining a last‑time‑buy strategy is advisable for qualification-protected designs. Original screening options such as /883 or equivalent high‑rel flows may be available on related variants, but the specific “ATEB” suffix should be confirmed against the manufacturer’s source‑control documentation to ensure the necessary level of processing and traceability.
