This document is the datasheet of IDT54/74FCT240/A/C, IDT54/74FCT241/A/C and IDT54/74FCT244/A/C, which introduces the features and characteristics of the products, including functions, pins, packages, speeds, etc.
The FAST CMOS Octal Buffer/Line Driver family from Integrated Device Technology is designed for memory, address, clock, and bus drivers, offering low power CMOS operation and options for radiation‑tolerant or enhanced versions. Variants A and C provide up to 55% faster performance than the original FAST devices, with commercial IOL of 64 mA and military IOL of 48 mA.
The datasheet details pin configurations for DIP, SOIC, and CERPACK packages, absolute maximum ratings, electrical characteristics, power‑supply behavior, and switching performance. Test circuits and waveform examples illustrate enable/disable timing and propagation delays. Ordering information lists part numbers for commercial and MIL‑STD‑883 Class B versions.
