description

11  
The ’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  
12 13 14 15 16 17 18  
NC – No internal connection  
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 I . The I circuitry disables the  
off  
off  
outputs, preventing damaging current backflow through the device when it is powered down.
