• 5Ω switches with 25Ω series resistor connect inputs
to outputs
• Direct bus connection when switches are ON
• Ultra Low Quiescent Power (0.2µA Typical)
– Ideally suited for notebook applications
• Packages available:
– 24-pin 150 mil wide plastic QSOP (Q)
– 24-pin 300 mil wide plastic SOIC (S)
Pericom Semiconductor’s PI5C series of logic circuits are produced
using the Company’s advanced 0.8 micron CMOS technology,
3 achieving industry leading performance.
The PI5C32861 is a 10-bit, 2-port bus switch designed with a low
ON resistance that permits inputs to be connected directly to
outputs. The bus switch creates no additional propagational delay
4 or additional ground bounce noise. The switches are turned ON
by the Bus Enable (BE) input signal. The PI5C32861 is designed
with an internal 25Ω resistor that reduces noise reflection in high-
speed applications
