DESCRIPTION
The 74ABT543A high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT543A Octal Registered Transceiver contains two sets of
D-type latches for temporary storage of data flowing in either
direction. Separate Latch Enable (LEAB, LEBA) and Output Enable
(OEAB, OEBA) inputs are provided for each register to permit
independent control of data transfer in either direction. The outputs
are guaranteed to sink 64mA.
FUNCTIONAL DESCRIPTION
The 74ABT543A contains two sets of eight D-type latches, with
separate control pins for each set. Using data flow from A to B as an
example, when the A-to-B Enable (EAB) input and the A-to-B Latch
Enable (LEAB) input are Low the A-to-B path is transparent. A
subsequent Low-to-High transition of the LEAB signal puts the A
data into the latches where it is stored and the B outputs no longer
change with the A inputs. With EAB and OEAB both Low, the
3-State B output buffers are active and display the data present at
the outputs of the A latches.
Control of data flow from B to A is similar, but using the EBA, LEBA,
and OEBA inputs.
