74FCT648TH

Buffers, Drivers, Receivers, Transceivers Overview

The IDT74FCT648TH is a high-performance, fast CMOS octal bus transceiver manufactured by Integrated Device Technology. It features eight non-inverting data paths with three-state outputs, designed for efficient bidirectional data transfer between buses. The device operates within a supply voltage range of 2.7V to 5.5V and supports TTL input levels. Key electrical characteristics include a maximum propagation delay of 5ns at 50pF load, with output drive capabilities of -24mA (high) and 24mA (low). It functions reliably across an industrial temperature range from -40°C to +85°C.
