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.

OEBA

Output-enable (OEAB and OEBA) inputs are

provided to control the transceiver functions.

Select-control (SAB and SBA) inputs are provided

to select either real-time or stored data for

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 selects

real-time data, and a high input selects stored

data. Figure 1 illustrates the four fundamental

bus-management functions that can be

performed with the ’ABT652A.

NC – No internal connection

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

attheappropriateclock(CLKABorCLKBA)inputs, regardlessoftheselect-orenable-controlinputs. WhenSAB

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.

To ensure the high-impedance state during power up or power down, OEBA should be tied to V

through a

pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver

(B to A). OEAB should be tied to GND through a pulldown resistor; the minimum value of the resistor is

determined by the current-sourcing capability of the driver (A to B).

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.
