description
These octal transceivers are designed specifically
for low-voltage (3.3-V) VCC operation, but with the
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.
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.
