PI3C3125LEX Diodes Incorporated

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 Description Features Near-Zero propagation delay Diodes PI3C3125 and PI3C3126 are 2.5 volt or 3.3 volt, 4-bit 5-ohm switches connect inputs to outputs bus switches designed with four individual 5-ohm bus switches 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 Rail-to-Rail, or 2.5V or 3.3V Switching pin is directly connected to the B pin for that particular gate. 5V I/O Tolerant e bTh us switch introduces no additional propagation delay or 2.5V Supply Voltage Operation additional ground bounce noise. Permits Hot Insertion e PTh I3C3125 device has active LOW enables, and the PI3C3126 Packaging (Pb-free & Green available): has active HIGH enables. It is very useful in switching signals that 14-pin 150-mil wide plastic SOIC (W) have high bandwidth (>400 MHz). 14-pin 170-mil wide plastic TSSOP (L) 16-pin 150-mil wide plastic QSOP (Q) Applications High Bandwidth Data Switching Hot Docking PI3C3125 Block Diagram PI3C3126 Block Diagram A0 B0 B0 A0 BE0 BE0 B1 A1 B1 A1 BE1 BE1 B2 A2 B2 A2 BE2 BE2 B3 A3 B3 A3 BE3 BE3 www.diodes.com September 2017 PI3C3125/PI3C3126 Diodes Incorporated Document Number DS40194 Rev 1-2 1A product Line of Diodes Incorporated PI3C3125/PI3C3126 Maximum Ratings (Above which the useful life may be impaired.
