Product Features

ProductDescription

2-Port Bus Switch

 

Near-zero propagation delay

5-Ohm switch connects inputs to outputs

Direct bus connection when switch is ON

32X384 function with flow through pinout makes board layout easier

Ultra-low quiescent power (0.2mA typical)

– ideally suited for notebook applications

Industrial operating temperature: –40°C to +85°C

Pericom Semiconductor’s PI3C series of Bus Switch circuits are produced using the Company’s advanced submicron CMOS technology, achieving industry leading speed.

The PI3C16210 is configured as a 20-bit, 2-port bus switch designed with a low ON resistance (5 Ohm) allowing inputs to be connected directly to outputs. The bus switch creates no additional propagational delay or additional ground bounce noise. The switch is turned ON by the Bus Enable (xOE) input signal.

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.
