descriptionThe CY74FCT652T consists of bus transceiver circuits, D-type flip-flops, and control circuitry arranged for
multiplexed transmission of data directly from the input bus or from the internal storage registers. GAB and GBA
inputs control the transceiver functions. Select-control (SAB and SBA) inputs select either real-time or
stored-data transfer. The circuitry used for select control eliminates the typical decoding glitch that occurs in
a multiplexer during the transition between stored and real-time data. A low input level selects real-time data,
and a high input level selects stored data.
Data on the A or B data bus, or both, can be stored in the internal D-type flip-flops by low-to-high transitions
of the appropriate clock (CPAB or CPBA) inputs, regardless of the select or enable levels of the control pins.
When SAB and SBA are in the real-time transfer mode, it also is possible to store data without using the internal
D-type flip-flops by simultaneously enabling GAB and GBA. In this configuration, each output reinforces its
input. Thus, when all other data sources to the two sets of bus lines are at high impedance, each set of bus
lines remains at its last state.
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.
