Description:
Pericom Semiconductor’s PI5C32X2245 is a 16-bit, 2-port bus
switch. Two enable signals (BEn) 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 reflections, thus eliminating the need
for an external terminating resistor.
