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. Enables GAB and GBA
are provided to control the transceiver functions. SAB and SBA control pins are provided to select whether
real-time or stored data is transferred. 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 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 bus, or both, can be stored in the internal D flip-flops by low-to-high transitions at the appropriate clock
pins (CAB or CBA) 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 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.
The 74ACT11651 is characterized for operation from − 40
°C to 85°C.
