description
The ’FCT541T noninverting buffers/line drivers
can 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 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.
