IDT 54/74FCT16244T/AT/CT/ET is a high-speed CMOS 16-bit buffer/line driver introduced by IDT. It features 0.5 MICRON CMOS Technology, high-speed, low-power CMOS replacement for ABT functions.
This datasheet describes the FAST CMOS 16‑bit buffer/line driver family from IDT, covering the high‑drive (FCT16244T), balanced‑drive (FCT162244T), light‑drive (FCT166244T) and bus‑hold (FCT162H244T) variants. It lists common features such as 0.5 µm CMOS technology, low leakage, ESD protection and a range of package options.
Technical sections provide pin‑out diagrams, absolute maximum ratings, input and output electrical characteristics, output‑drive capabilities, power‑supply behavior and switching performance. Ordering information and temperature specifications for commercial and military grades are also included.
