Description
Pericom Semiconductor’s PI5C34X2245 is a 32-bit,
2-port
turn the switches on. The bus switch creates no
additional propagational delay or additional ground bounce noise.
The device has a built-in 25Ω resistor to reduce noise resulting
from reflection, thus eliminating the need for an external
terminating resistor.
