PI3C3125LE

A product Line of Diodes Incorporated PI3C3125/PI3C3126 2.5V/3.3V, High Bandwidth, Hot Insertion,4-Bit, 2-Port Bus Switch with Individual Enables Features Description ÎÎ Near-Zero propagation delay ÎÎ 5-ohm switches connect inputs to outputs ÎÎ High Bandwidth (>400 MHz) ÎÎ Rail-to-Rail, or 2.5V or 3.3V Switching ÎÎ 5V I/O Tolerant ÎÎ 2.5V Supply Voltage Operation ÎÎ Permits Hot Insertion ÎÎ Packaging (Pb-free & Green available): Diodes’ 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. 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). – 14-pin 150-mil wide plastic SOIC (W) – 14-pin 170-mil wide plastic TSSOP (L) – 16-pin 150-mil wide plastic QSOP (Q) Applications ÎÎ High Bandwidth Data Switching ÎÎ Hot Docking PI3C3126 Block Diagram PI3C3125 Block Diagram A0 A0 B0 BE0 BE0 A1 A1 B1 A2 B2 A3 B3 Document Number DS40194 Rev 1-2 B3 BE3 BE3 PI3C3125/PI3C3126 B2 BE2 BE2 A3 B1 BE1 BE1 A2 B0 1 www.diodes.com September 2017 Diodes Incorporated A product Line of Diodes Incorporated PI3C3125/PI3C3126 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.
