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. The select-control (SAB and SBA) inputs are
provided to select whether real-time or stored data is transferred. 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 74AC11651.
Data on the A or B bus, or both, can be stored in the internal D flip-flops by low-to-high transitions at the
appropriate clock (CLKAB or CLKBA) inputs regardless of the select- or enable-control pins. When SAB and
SBA are in the real-time transfer mode, it is also 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. Thus, when
all the other data sources to the two sets of bus lines are at high impedance, each set will remain at its last state.
The 74AC11651 is characterized for operation from – 40
°C to 85°C.
