ProductDescription

Pericom Semiconductor’s PI3C series of bus switch circuits are produced using the Company’s advanced submicron CMOS technology, achieving industry leading performance.

PI3C16226 is a 12-to 24-bit multiplexer/demultiplexer bus switch. Industry leading advantages include a zero propagation delay of 500ps, resulting from 9-ohm channel resistance and low I/O capacitance. A1 port demultiplexes to either 1B or 2B and the switch is bidirectional.

Application

Provides Memory Module switching.

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.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.

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