description
The SN54LVC652A octal bus transceiver and
register is designed for 2.7-V to 3.6-V V
CC
operation, and the SN74LVC652A octal bus
transceiver and register is designed for 1.65-V to
3.6-V V
CC
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
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.
