A product Line of Diodes Incorporated 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 PI3C3126 is a 2.5 volt or 3.3 volt, 4-bit bus switch 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) • 2.5V/3.3V Supply Voltage Operation • Rail-to-Rail, or 2.5V or 3.3V Switching • 5V I/O Tolerant 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 170-mil wide plastic TSSOP (L) 14-Pin Configuration – 16-pin 150-mil wide plastic QSOP (Q) Applications BE0 A0 B0 BE1 A1 B1 GND • High Bandwidth Data Switching • Hot Docking Block Diagram B0 A0 BE0 NC BE0 A0 B0 BE1 A1 B1 GND BE1 B2 A2 BE2 B3 A3 BE3 1 16 2 15 3 16-PIN 14 4 Q16 13 5 12 6 11 7 10 8 9 Vcc BE3 A3 B3 BE2 A2 B2 NC Truth Table(1) Pin Description VCC GND Vcc BE3 A3 B3 BE2 A2 B2 16-Pin Configuration B1 A1 Pin Name BEn A3 - A0 B3 - B0 1 14 2 13 3 14-PIN 12 4 L14 11 5 10 6 9 7 8 Description Switch Enable Bus A Bus B BEn X L H Power Ground All trademarks are property of their respective owners.

For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading. 3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second. 4. Measured by the voltage drop between A and B pin at indicated current through the switch. ON resistance is determined by the lower of the voltages on the two (A,B) pins.

Units 0.25 1.5 6.5 1.5 5.5 ns Notes: 1. This parameter is guaranteed but not tested on Propagation Delays. 2. 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.
