description
The ’FCT244T 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.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.

On products compliant to MIL-PRF-38535, all parameters are tested
unless otherwise noted. On all other products, production
processing does not necessarily include testing of all parameters.
