description

The ’FCT240T devices are octal buffers and line

drivers designed to be employed as memory

address drivers, clock drivers, and

bus-oriented transmitters/receivers. These devices provide speed and drive capabilities equivalent to their

fastest bipolar logic counterparts, while reducing power consumption. The input and output voltage levels allow

direct interface with TTL, NMOS, and CMOS devices without external components.

These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the

outputs, preventing damaging current backflow through the device when it is powered down.
