description
These devices consist of bus-transceiver circuits,
D-type flip-flops, and control circuitry arranged for
multiplexed transmission of data directly from the
data bus or from the internal storage registers.
Output-enable (OEAB and OEBA) inputs are
provided to control the transceiver functions.
Select-control (SAB and SBA) inputs are provided
to select 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. Figure 1
illustrates the four fundamental bus-management functions that can be performed with the octal bus
transceivers and registers.
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 at
the appropriate clock (CLKAB or CLKBA) terminals, regardless of the select- or output-control terminals. When
SAB and SBA are in the real-time transfer mode, it is possible to store data without using the internal D-type
flip-flops by simultaneously enabling OEAB and OEBA. In this configuration, each output reinforces its input.
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.
