PI3B16215

3.3V, Hot Insertion, 20-Bit FET

BusSwitch w/Precharged Outputs

Product Features

Product Description

PericomSemiconductorsPI3Bseriesoflogiccircuitsareproduced

using the companys advanced 0.35 micron CMOS Technology.

Near Zero Propagation Delay

5Ω Switches Connect Between Two Ports

FastSwitchingSpeed:4.5nsmax.

Permits Hot Insertion

ThePI3B16215provides20-bitsofhigh-speedbusswitching.Low

on-state resistance of the switch allows connections to be made

with minimal propagation delay. The device also precharges the

B-port to a user-selectable bias voltage (BIASV) to minimize live-

insertion noise.

Isolation during Power-Off conditions

B-Port Outputs are precharged by Bias Voltage

to minimize signal distortion during live insertion

Thedeviceisorganizedasdual 10-bitbusswitcheswithindividual

output-enable (OE) inputs. When OE is LOW, the corresponding

10-bit bus switch is on and port A is connected to port B. When OE

isHIGH, theswitchisopen, ahigh-impedancestateexistsbetween

the two ports, and port B is precharged to BIASV through the

equivalent of a 10-kΩ resistor.

Package options include:

48-pin150-milwideplasticBQSOP(B)

48-pin240-milwideplasticTSSOP(A)

48-pin300-milwideplasticSSOP(V)

To ensure the high-impedance state on power up or power down,

OE should be tied to V through a pullup resistor; the minimum

valueoftheresistorisdeterminedbythecurrent-sinkingcapability

of the driver connected to OE.
