This document introduces the features and characteristics of 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.
This document provides a datasheet description for the IDT family of FAST CMOS octal buffers and line drivers. The devices are designed to be employed as memory and address drivers, clock drivers, and bus-oriented transceivers which provide improved board density.
The series includes standard speed grades (Std., A, C, D) with high drive outputs. Specific models like the FCT2240T, FCT2244T, and FCT2541T feature balanced output drive with current limiting resistors to reduce ground bounce and switching noise. The document details pin configurations for various package types including DIP, SOIC, SSOP, QSOP, CERPACK, and LCC.
