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 I . The I circuitry disables the
off
off
outputs, preventing damaging current backflow through the device when it is powered down.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
