PI3C3861-A 2.5V/3.3V, High Bandwidth, Hot-Insertion, 10-Bit, 2-Port, Bus Switch Features Description Near-Zero propagation delay Pericom Semiconductor s PI3C series of logic circuits are produced 5-ohm switches connect inputs to outputs using the company s advance submicron CMOS technology, achieving industry leading performance. High bandwidth (>400 MHz) Rail-to-rail 2.5V or 3.3V switching The PI3C3861-A is a 10-bit, 2.5volt or 3.3 volt, 2-port bus switch designed with a low On-Resistance (5-ohm) allowing inputs to be 5V I/O Tolerant connected directly to outputs. The bus switch creates no additional 2.5V Supply Voltage Operation propagational delay or additional ground bounce noise. The switches Permits Hot-Insertion are turned ON by the Bus Enable (BE) input signal. This device Packaging (Pb-free & Green Available): is very userful in switching signals that have high bandwidth 24-pin 150-mil wide plastic QSOP (Q) (>400 MHz). 24-pin 173-mil wide plastic TSSOP (L) Applications High bandwidth data switching Hot Docking Block Diagram Pin Con guration A B 0 0 NC 1 24 V CC A 2 23 B 0 E A 3 22 B 1 0 A 4 21 B 2 1 A 5 20 B 3 2 A B 9 9 6 19 A B 4 3 7 18 A B 5 4 8 17 A B 6 5 9 16 A B 7 6 10 15 A B 8 7 11 14 A B 9 8 12 13 GND B 9 BE (1) Pin Description Truth Table Function BE A09 Pin Name Description BE Bus Enable Input (Active LOW) Disconnect H Hi-Z A Bus A 09 Connect L B 09 B Bus B 09 Note: 1.
