PI3B16210
PI3B162210 (25 Ohms)
3.3V, Hot Insertion 20-Bit, 2-Port BusSwitch
Product Features
Near-zero propagation delay
ProductDescription
Pericom Semiconductors PI3B series of BusSwitch circuits are
produced using the Companys advanced submicron CMOS
technology, achieving industry leading speed.
5-ohm or 25-ohm switches connect inputs to outputs
Fast Switching Speed: 4.5ns max.
32x384 function with flow-through pinout make board
layout easier
Permits Hot Insertion.
VCC OperatingRange:3.0Vto3.6V
Industrialoperatingtemperature:40°Cto+85°C
ThePI3B16210isconfiguredasa3.3volt20-bit,2-portbusswitch
designed with a low ON resistance (5 ohms) allowing inputs to be
connecteddirectlytooutputs.Thebusswitchcreatesnoadditional
propagational delay or additional ground bounce noise. Switches
are turned ON by the Bus Enable (xOE) input signal.
Packagesavailable:
The PI3B162210 device has a built-in 25-ohm series resistor to
reduce noise resulting from reflections, thus eliminating the need
for an external terminating resistor.
