PI74LCX16952
Fast CMOS 3.3V 16-Bit
16-Bit Registered Transceivers
Product Description
Pericom Semiconductors PI74LCX series of logic circuits are
produced using the Companys advanced 0.6 micron CMOS
technology, achieving industry leading speed grades.
The PI74LCX16952 is a 16-bit registered 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. The data present on the A port will be clocked on the B
register when xCLKAB toggles from LOW-to-HIGH. The xOEAB
control performs the output enable function on the B port. Control
of data from B to A is similar, but uses the xCEAB, xCLKAB, and
xOEAB inputs. By connecting the control pins of the two independent
transceivers together, a full 16-bit operation can be achieved. The
output buffers are designed with a Power-Off disable allowing "live
insertion" of boards when used as backplane drivers.
The PI74LCX16952 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.
