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.
These devices are fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the
outputs, preventing damaging current backflow through the device when it is powered down.
