DESCRIPTION
The 74LVC543A is a high-performance, low-power,
low-voltage, Si-gate CMOS device, 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 inputs (pins LE
inputs (pins OE
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 pins A to B, for example, the A to B enable input
(pin E
A0 to A7 or take data from pins B0 to B7, as indicated in
the “Function table”. With pin E
the A to B latch enable input (pin LE
latches transparent; a subsequent LOW-to-HIGH
transition on pin LE
where it is stored and the B outputs no longer change with
the A inputs. With pins E
3-state B output buffers are active and display the data
present at the outputs of the A latches.
