PI5C16209
PI5C162209 (25Ω)
18-Bit Bus Exchange Switch
Product Features
Product Description
Near-zero propagation delay
Pericom Semiconductors PI5C series of logic circuits are produced
using the Companys advanced 0.8 micron CMOS technology.
5W switches connect inputs to outputs
Direct bus connection when switches are ON
ThePI5C16209andPI5C162209are18-bitbusexchangeswitches
designed with a low ON resistance (5Ω) allowing inputs to be
connected directly to outputs. This device operates as a 18-bit bus
switch or a 9-bit exchanger, which provides data exchanging
between the four signal ports via the data select pins (S0-S2).
Ultra-low quiescent power (0.2µA typical)
Ideally suited for notebook applications
Industrialoperatingtemperature:40°Cto+85°C
AvailablePackages:
The PI5C162209 device has a built-in 25-ohm series resistor to
reduce noise because of reflections, thus eliminating the need for
an external terminating resistor.
