25 OEBA

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

NC – No internal connection

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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
