3.3Volt, 24-Bit

Features

Description

Mux/Demux BusSwitch

 

Near-zero propagation delay

Pericom Semiconductor’s PI3B series of logic circuits are produced

• 5 Ω switches connect inputs to outputs

using the Company’s advanced 0.35 micron CMOS technology.

• Fast Switching Speed - 5ns (max.)(16292)

The PI3B16292 and PI3B162292 are 3.3 volt, 12-bit to 24-bit

• Internal 500 Ω pull-down on A2 ports

Mux/Demux Bus switches designed with a low ON resistance

• Ultra-low quiescent power (0.2µA typical) – Ideally

allowing inputs to be connected directly to outputs.

 

suited for notebook applications

The PI3B162292 device has a built-in 25-ohm series resistor

• Vcc Operating Range : 3.0V to 3.6V

to reduce noise resulting from reflections, thus eliminating the

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

need for an external terminating resistor.

A2 port is not externally connected and, as a result, has an internal

• Make-before-break switching

500-ohm pulldown resistor to ground.

Notes:

1.For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.

2.Typical values are at Vcc = 3.3V, TA = 25°C ambient and maximum loading.

3.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.

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