Product Description
Pericoms PI5X series of high density logic circuits are produced using
the Companys advanced submicron CMOS technology to achieve
industry leading performance.
The PI5X1018 is an 18-bit, 10-port crossbar switch designed with a
low ON resistance allowing inputs to be connected directly to
outputs. The crossbar creates a low propagation delay and adds low
additional ground bounce noise. Switches are turned ON in groups
of 18 allowing any combination of connected ports. An additional
bias voltage pin, VBIAS, permits control of internal pull-up
resistors that can be used for pin termination. Several of these
devices can be grouped together for wider data and control paths.
Product Features
Full 10-way crossbar
Independent controls for all ports
