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.
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.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The package thermal impedance is calculated in accordance with JESD 51-7.

† Typical values are at VCC = 5 V, TA = 25°C.
‡ Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or
sample-and-hold techniques are preferable to minimize internal chip heating and more accurately reflect operational values. Otherwise, prolonged
shorting of a high output can raise the chip temperature well above normal and cause invalid readings in other parametric tests. In any sequence
of parameter tests, IOS tests should be performed last.
