Octal Registered Bus Transceivers With 3-State Outputs And Series Output Resistors

The CY74FCT2646T consists 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-control (DIR) inputs determine the transceiver function. On-chip termination resistors at the outputs reduce system noise caused by reflections, so that the CY74FCT2646T CAN replace the CY74FCT646T in an existing design.
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 active 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
This device is 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.
