Integrated Device Technology IDT54/74FCT623T/AT/CT Octal Bus Transceiver Datasheet
This document is a technical datasheet for the IDT54/74FCT623T, AT, and CT series of fast CMOS octal bus transceivers. These devices are designed for asynchronous two-way communication between data buses with true TTL input and output compatibility.
Key features include standard, A, and C speed grades; low input and output leakage currents; high drive outputs capable of sinking 64mA and sourcing up to 15mA; and a power-off disable capability that permits live insertion. The transceivers are available in commercial and military temperature ranges across DIP, SOIC, CERPACK, and LCC packages.
