Product Description

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

The PI3C16211 is a 24-bit bus switch designed with a low ON resistance allowing inputs to be connected directly to outputs. This device operates as a 24-bit or a 12-bit bus switch, which provides high speed bus 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.
