PI5C6801C

10-Bit Bus Switch with Precharged Outputs

for Live Insertion and –2V Undershoot Protection

ProductDescription

Pericom’sSemiconductor’sPI5Cseriesoflogiccircuitsareproduced

using the Company’s advanced submicron CMOS technology,

achieving industry leading performance.

The PI5C6801C is a 10-bit bus switch with low on-state resistance.

The bus switch creates no additional propagation delay. The device

also precharges the B port to a user-selectable bias voltage (BIASV)

tominimizelive-insertionnoise.

The switch is turned on by a single enable (ON) input. When ON is

LOW, the switch is on and port A is connnected to port B. When ON

is HIGH, the switch between port A and port B is open and the B port

is precharged to BIASV through the equivalent of a 10-kΩ resistor.

ProductFeatures

• Undershoot protection on A-port only

• Industrial Operation Temperature: –40ºC to +85ºC

• Near Zero propagation delay

• Outputs are pre-charged by bias voltage to minimize

signal distortion during live insertion
