description

Theseoctaltransceiversaredesignedspecifically

for low-voltage (3.3-V) V operation, but with the

12 13 14 15 16 17 18

capability to provide a TTL interface to a 5-V

system environment.

The ’LVT543 contain 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.

NC – No internal connection

The A-to-B enable (CEAB) input must be low in order 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 puts

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 from B to A is similar but requires using the CEBA,

LEBA, and OEBA inputs.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

UNLESS OTHERWISE NOTED this document contains PRODUCTION

DATA information current as of publication date. Products conform to

specifications per the terms of Texas Instruments standard warranty.

Production processing does not necessarily include testing of all

parameters.
