High impedance when V
CC
= 0V
DESCRIPTION
The 74LVC543A is a high–performance, low–power, low–voltage,
Si–gate CMOS device and superior to most advanced CMOS
compatible TTL families.
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 (LE
AB
, LE
BA
) and output
enable (OE
AB
, OE
BA
) inputs are provided for each register to permit
independent control of inputting and outputting 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 A to B, for example, the
A–to–B enable (E
AB
) input must be LOW in order to enter data from
A
0

or take data from B
0

, as indicated in the function table.
With E
AB
LOW, a LOW signal on the A–to–B latch enable (LE
AB
)
input makes the A–to–B latches transparent; a subsequent LOW–to
HIGH transition of the LE
AB
signal puts the A data into the latches
where it is stored and the B outputs no longer change with the A
inputs. With E
AB
and OE
AB
both low, the 3–state B output buffers
are active and display the data present at the outputs of the A
latches
