PI3C16211

3.3V, High Bandwidth 24-Bit Bus Switch

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.

Product Features

• Near-zero propagation delay

• 5 Ohm switches connect inputs to outputs

• Direct bus connection when switches are ON

• Ultra-low quiescent power (0.2mA typical)

– Ideally suited for notebook applications

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

• Packages available:

– 56-pin 240-mil wide thin plastic TSSOP (A)

– 56-pin 300-mil wide plastic SSOP (V)
