description
The SN74F543 octal transceiver 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 outputs are
characterized to sink 24 mA while the B outputs
are characterized to sink 64 mA.
The A-to-B enable (CEAB) input must be low in order to enter data from A or to output data from B. Having CEAB
low and LEAB low makes the A-to-B latches 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.
The SN74F543 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count
and functionality of standard small-outline packages in less than half the printed-circuit-board area.
The SN74F543 is characterized for operation from 0
°C to 70°C.

A-to-B data flow is shown; B-to-A flow control is the
same except that it uses CEBA, LEBA, and OEBA.
