PI5C34X2245
32-Bit, 2-Port Bus Switch with 25Ω Series Resistor

Pericom Semiconductor’s PI5C34X2245 is a 32-bit, 2-port bus switch. Four 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 reflection, thus eliminating the need for an external terminating resistor.
