This data sheet provides detailed information about the FCT646T/648T/652T and FCT2646T/2652T, including features, characteristics, and applications.
The IDT54/74FCT family are fast CMOS octal transceivers/registers that provide 3‑state D‑type flip‑flops and multiplexed data transfer. They are offered in both non‑inverting and inverting versions and support real‑time or stored data modes.
Key features include low leakage (<1 µA), true TTL compatibility, high‑drive and resistor‑drive output options, and operation over commercial (‑40 °C to +85 °C) and military (‑55 °C to +125 °C) temperature ranges. The devices are supplied in a wide variety of packages such as DIP, SOIC, SSOP, QSOP, TSSOP, CERPACK and LCC, and the document provides full pin‑out tables, functional timing diagrams, absolute‑maximum ratings, and power‑supply characteristics.
