description

The SN54LVC652A octal bus transceiver and

operation, and the SN74LVC652A octal bus

transceiver and register is designed for 1.65-V to

28 27 26

OEBA

3.6-V V

operation.

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 whether real-time or stored data is

transferred. The circuitry used for select control

eliminates the typical decoding glitch that occurs

NC – No internal connection

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 are

performed with the ’LVC652A.

Data on the A or B data bus, or both, is 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.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators

in a mixed 3.3-V/5-V system environment.
