Product Description
Pericom Semiconductor’s PI74LCX series of logic circuits are
produced using 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 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 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.
