DESCRIPTION/ORDERING INFORMATION

This octal registered transceiver is designed for 1.65-V to 3.6-V V_CCoperation.

The SN74LVC543A contains two sets of D-type latches for temporary storage of data flowing in either direction.

Separate latch-enable (LEAB or LEBA) and output-enable (OEAB or OEBA) inputs are provided for each register

to permit independent control in either direction of data flow.

The A-to-B enable (CEAB) input must be low to enter data from A or to output data from B. If CEAB is low and

LEAB is low, the A-to-B latches are transparent; a subsequent low-to-high transition of LEAB places the A

latches in the storage mode. With CEAB and OEAB both low, the 3-state B outputs are active and reflect the

data present at the output of the A latches. Data flow for B to A is similar to that of A to B, but uses CEBA, LEBA,

and OEBA.

This device is fully specified for partial-power-down applications using I_off. The I_offcircuitry disables the outputs,

preventing damaging current backflow through the device when it is powered down.

To ensure the high-impedance state during power up or power down, OE should be tied to V_CCthrough a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

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.
