DESCRIPTION
The 74LVT16543A is a high-performance BiCMOS product
designed for V
CC
operation at 3.3V. The device can be used as two
8-bit transceivers or one 16-bit transceiver.
The 74LVT16543A 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 (nEAB) input and the A-to-B Latch
Enable (nLEAB) input are Low, the A-to-B path is transparent.
A subsequent Low-to-High transition of the nLEAB signal puts the A
data into the latches where it is stored and the B outputs no longer
change with the A inputs. With nEAB and nOEAB 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 nEBA,
nLEBA, and nOEBA inputs.
Active bus-hold circuitry is provided to hold unused or floating data
inputs at a valid logic level.
