Description
Pericom Semiconductor’s PI3C32X384, is a 2.5V or 3.3Volt,
highbandwidth 20-bit, 2-port bus switches designed with a low
Onresistance allowing inputs to be connected directly to out-
puts. The bus switch creates no additional propagational delay
or additional ground bounce noise. The switches are turned ON
by the Bus Enable (BE) input signal. Four bus enable signals are
provided, one for each of the upper and lower five bits of the two
10-bit buses.
Applications
ÎÎHigh Bandwidth Data switching
ÎÎHot Docking

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading.
3. Measured by the voltage drop between A and B pin at indicated current through the switch. ON resistance is determined by the lower of the voltages on the two
(A,B) pins.
4. This parameter is determined by device characterization but is not production tested.
