description
The ’FCT573T devices consist of eight latches with 3-state outputs for bus-organized applications. When the
latch-enable (LE) input is high, the flip-flops appear transparent to the data. Data that meets the required setup
times are latched when LE transitions from high to low. Data appears on the bus when the output-enable (OE)
input is low. When OE is high, the bus output is in the high-impedance state. In this mode, data can be entered
into the latches. The ’FCT573T devices are identical to the ’FCT373T devices, except for the flow-through
pinout of the ’FCT573T, which simplifies board design.
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.

standard warranty. Production processing does not necessarily include
testing of all parameters.
