The FCT16823AT/BT/CT/ET and FCT162823AT/BT/CT/ET are 18-bit bus interface registers built using advanced, dual metal CMOS technology. These high-speed, low-power registers with clock enable (xCLKEN) and clear (xCLR) controls are ideal for parity bus interfacing in high-performance synchronous systems.
The FCT16823AT/BT/CT/ET and FCT162823AT/BT/CT/ET are 18‑bit CMOS bus interface registers built with dual‑metal technology. They offer high‑speed, low‑power operation with clock‑enable and clear controls, and can be configured as two 9‑bit registers or a single 18‑bit register. The devices include power‑off disable outputs for live board insertion and balanced output drivers with current limiting.
The datasheet provides detailed pin configurations, functional block diagrams, absolute maximum ratings, DC electrical characteristics, power‑supply and switching characteristics, as well as ordering information for commercial and military temperature ranges.
