descriptionThe ’FCT646T devices consist of a bus
transceiver circuit with 3-state, D-type flip-flops,
and control circuitry arranged for multiplexed
transmission of data directly from the input bus or
from the internal registers. Data on the A or B bus
is clocked into the registers as the appropriate
clock pin goes to a high logic level. Output-enable (G) and direction (DIR) inputs control the transceiver function.
In the transceiver mode,data present at the high-impedance port can be stored in either the A or B register, or
in both. Select controls (SAB, SBA) can multiplex stored and real-time (transparent mode) data. DIR determines
which bus receives data when G is low. In the isolation mode (G is high), A data can be stored in the B register
and/or B data can be stored in the A register.
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.
