description

The ’FCT540T inverting buffers/line drivers can

be employed as memory address drivers, clock

drivers, and bus-oriented transmitters/receivers.

These devices provide speed and drive capabili-

ties equivalent to their fastest bipolar-logic

counterparts, while reducing power dissipation.

The input and output voltage levels allow direct

interface with TTL, NMOS, and CMOS devices

without external components.
