PI5C16210
PI5C162210 (25ohm)
20-Bit, 2-Port Bus Switch
Product Description:
Product Features:
Near-zero propagation delay
Pericom Semiconductors PI5C series of BusSwitch circuits are
produced in the Companys advanced sub-micron CMOS
technology, achieving industry leading speed.
5ohm or 25ohm switches connect inputs to outputs
Direct bus connection when switches are ON
32X384 function with flow through pinout make board
layout easier
ThePI5C16210isconfiguredas20-bit,2-portbusswitchesdesigned
with a low ON resistance (5ohm) allowing inputs to be connected
directly to outputs. The bus switch creates no additional
propagationaldelayoradditionalgroundbouncenoise.Theswitches
are turned ON by the Bus Enable (xOE) input signal.
Ultra-low quiescent power (0.2µA typical)
ideally suited for notebook applications
Industrial operating temperature: 40°C to +85°C
Packages available:
The PI5C162210 device has a built-in 25-ohm series resistor to
reduce noise resulting from reflections, thus eliminating the need
for an external terminating resistor.
