PI3C3125 PI3C3126 2.5V/3.3V, High Bandwidth, Hot Insertion,4-Bit, 2-Port Bus Switch with Individual Enables Features Description • Near-Zero propagation delay Pericom Semiconductor’s PI3C3125 and PI3C3126 are 2.5 volt or 3.3 volt, 4-bit bus switches designed with four individual 5-ohm bus switches with fast indiviual enables in an industry standard 74XX125/126 pinout. When enabled via the associated Bus Enable pin, the “A” pin is directly connected to the “B” pin for that particular gate. The bus switch introduces no additional propagation delay or additional ground bounce noise. • 5-ohm switches connect inputs to outputs • High Bandwidth (>400 MHz) • Rail-to-Rail, or 2.5V or 3.3V Switching • 5V I/O Tolerant • 2.5V Supply Voltage Operation The PI3C3125 device has active LOW enables, and the PI3C3126 has active HIGH enables. It is very useful in switching signals that have high bandwidth (>400 MHz). • Permits Hot Insertion • Packaging (Pb-free & Green available): – 14-pin 150-mil wide plastic SOIC (W) – 14-pin 170-mil wide plastic TSSOP (L) – 16-pin 150-mil wide plastic QSOP (Q) – 16-contact TFDN (ZJ) Applications • High Bandwidth Data Switching • Hot Docking PI3C3125 Block Diagram A0 PI3C3126 Block Diagram B0 A0 BE0 A1 BE0 B1 A1 BE1 A2 B2 A2 B2 BE2 B3 A3 BE3 07-0240 B1 BE1 BE2 A3 B0 B3 BE3 1 PS8153H 10/25/07 PI3C3125/PI3C3126 2.5V/3.3V, High Bandwidth, Hot Insertion,4-Bit, 2-Port Bus Switch with Individual Enables Maximum Ratings (Above which the useful life may be impaired.

The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side.
