PS2092A 01/23/97

Product Description

Pericom Semiconductor’s PI74LCX series of logic circuits are
produced in the Company’s advanced 0.6 micron CMOS technology
achieving high speed while maintaining low power operation.

The PI74LCX16543 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 A­to-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 PI74LCX16543 can be driven from either 3.3V or 5.0V devices
allowing this device to be used as a translator in a mixed

3.3V/5.0V system.
