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
NC – No internal connection
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.

description (continued)
To ensure the high-impedance state during power up or power down, OEBA should be tied to VCC through a
pullup resistor and OEAB should be tied to GND through a pulldown resistor; the minimum value of the resistor
is determined by the current-sinking/current-sourcing capability of the driver.
The SN54LVC652A is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74LVC652A is characterized for operation from –40°C to 85°C.

† The data-output functions can be enabled or disabled by a variety of level combinations at OEAB or OEBA. Data-input functions always are
enabled; i.e., data at the bus terminals is stored on every low-to-high transition of the clock inputs.
‡ Select control = L; clocks can occur simultaneously.
Select control = H; clocks must be staggered to load both registers.
