3.3V, 10-Bit, 2-Port BusSwitch
with SSTL-2 Enable
Product Features
• Near zero propagation delay
• 20 Ohm switches connect inputs to outputs
• Fast Switching Speed - 3.8ns (max.)
• Packages available:
– 24-pin 150 mil wide plastic QSOP (Q)
– 24-pin 173 mil wide plastic TSSOP (L)
Product Description
Pericom’s Semiconductor’s PI3B series of logic circuits are
produced using the Company’s advanced sub micron CMOS
technology, achieving industry leading performance.
The PI3B3863 is a 10-bit, 3.3 volt two-port bus switch designed
with a low ON resistance allowing inputs to be connected
directly to outputs. 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,
which is SSTL-2 compatible.

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.
