The document introduces the IDT54/74FCT240/244T/AT/CT/DT - 2240/2244T/AT/CT, IDT54/74FCT540/541/2541T/AT/CT FAST CMOS OCTAL BUFFER/LINE DRIVER MILITARY AND COMMERCIAL TEMPERATURE RANGES. It is a fast CMOS octal buffer/line driver, built using an advanced dual metal CMOS technology.
The IDT fast CMOS octal buffer/line drivers are available in a range of packages (DIP, SOIC, SSOP, QSOP, CERPACK, LCC) and support both commercial and military temperature ranges. They feature low input and output leakage, true TTL compatibility, and high‑drive output currents suitable for memory, address, clock, and bus applications.
The datasheet provides detailed pin configurations, absolute maximum ratings, DC electrical characteristics, switching performance, and power‑supply specifications, along with test circuit diagrams and ordering information for the various device variants (standard, radiation‑tolerant, and enhanced).
