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 ip-ops 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 ow-through

pinout of the ’FCT573T, which simplifies board design.

These devices are fully specied 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.
