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 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 selects

real-time data, and a high input selects stored

data. Figure 1 illustrates the four fundamental

bus-managementfunctionsthatcanbeperformed

with the ′ABT652.

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 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 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).

The SN74ABT652 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count

and functionality of standard small-outline packages in less than half the printed-circuit-board area.
