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

illustrates the four fundamental

bus-management functions that can be

performed with the ’ABT651 devices.

NC – No internal connection

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 also 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

the other data sources to the two sets of bus lines are at high impedance, each set 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).

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