description

These octal transceivers are designedspecifically

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

capability to provide a TTL interface to a 5-V

system environment.

NC – No internal connection

The ’LVTH543 devices 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.

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 puts the A latches

inthestoragemode. WithCEABandOEABbothlow, the3-stateBoutputsareactiveandreflectthedatapresent

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.
