PI74LPT16543
Fast CMOS 16-Bit Latched Transceivers
Product Description
Pericom Semiconductor’s PI74LPT series of logic circuits are pro-
duced in the Company’s advanced 0.6 micron CMOS technology,
achieving industry leading speed grades.
The PI74LPT16543 is 16-bit latched transceivers organized with
two sets of eight D-type latches with separate input and output
controls for each set. For data flow from A to B, for example, the A-
to-B Enable (xCEAB) input must be LOW in order to enter data
from xAx or to take data from xBx, as indicated in the Truth Table.
With xCEAB LOW, a LOW signal makes the A-to-B latches
transparent; a subsequent LOW-to-HIGH transition of the xLEAB
signal puts the A latches in the storage mode and their outputs no
longer change the A inputs. With xCEAB and xOEAB both LOW,
the 3-state B output buffers are active and reflect the data present at
the output of the A latches. Control of data from B to A is similar,
but uses the xCEAB, xLEAB, and xOEAB inputs.
The PI74LPT16543 can be driven from either 3.3V or 5.0V devices
allowing this device to be used as a translator in a mixed 3.3/5.0V
system.
