General description
The 74LVC543A is an octal registered transceiver containing two sets of D-type latches
for temporary storage of the data flow in either direction. Separate latch enable inputs
(pins LEAB and LEBA) and output enable inputs (pins OEAB and OEBA), are provided for
each register. The separate inputs permit independent control of input and output in either
direction of the data flow.
The 74LVC543A contains eight D-type latches, with separate inputs and controls for each
set. For data flow from pins A to B, the A to B enable input (pin EAB) must be LOW. The
LOW state enables data entry from pins A0 to A7 or from pins B0 to B7, as indicated in
Table 3. With pin EAB LOW, a LOW signal on the A to B latch enable input (pin LEAB)
makes the A to B latches transparent. A subsequent LOW-to-HIGH transition on pin LEAB
puts the A data into the latches where it is stored. The B outputs no longer change with
the A inputs. With pins 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.
