A product Line of Diodes Incorporated PI3C3126 2.5V/3.3V, High Bandwidth, Hot Insertion,4-Bit, 2-Port Bus Switch with Individual Enables Description Features Pericom Semiconductor s PI3C3126 is a 2.5 volt or 3.3 volt, 4-bit Near-Zero propagation delay bus switch designed with four individual 5-ohm bus switches 5-ohm switches connect inputs to outputs with fast indiviual enables in an industry standard 74XX125/126 High Bandwidth (>400 MHz) pinout. When enabled via the associated Bus Enable pin, the A 2.5V/3.3V Supply Voltage Operation pin is directly connected to the B pin for that particular gate. The bus switch introduces no additional propagation delay or Rail-to-Rail, or 2.5V or 3.3V Switching additional ground bounce noise. 5V I/O Tolerant The PI3C3126 has active HIGH enables. It is very useful in Permits Hot Insertion switching signals that have high bandwidth (>400 MHz).
