ProductFeatures

Near-zero propagation delay

Lownoise,25Ohmversion(PI3B32384)

5 Ohm switches connect inputs to outputs (PI3B3384)

3.3V, Hot Insertion 10-Bit, 2-Port, BusSwitch

ProductDescription

Pericom Semiconductor’s PI3B series of logic circuits are produced using the Company’s advanced submicron CMOS technology, achieving industry leading performance.

Fast Switching Speed - 4.5ns max.

Permits Hot Insertion.

Ultra-low quiescent power (0.1µA typical)

Ideally suited for notebook applications

Package:

24-pin 150-mil wide plastic QSOP (Q)

24-pin 173-milwideplasticTSSOP(L)

ThePI3B3384andPI3B32384are3.3Volt,10-bit,2-portbusswitches designed with a low ON resistance allowing inputs to be connected directlytooutputs.Thebusswitchcreatesnoadditionalpropagational delay or additional ground bounce noise. Switches are turned ON by the Bus Enable (BE) input signal. Two bus enable signals are provided, one for each of the upper and lower five bits of the two 10-bit buses. The PI3B32384 is designed with an internal 25 Ohm resistor reducing noise reflection in high-speed applications.

Notes:

1.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.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.

4.This parameter is determined by device characterization but is not production tested.
