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 Multiple parts can be used for wider data paths Near-zero propagation delay 25W switches connect input to outputs Direct bus connection when switches are ON Ultra Low Quiescent Power (1mA Typical) Packages available: - 256-pin BGA (NA256)

The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load capacitance. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. 4.
