24-Bit Bus-Exchange Switch

Product Features:

• Near-zero propagation delay

• 5Ω switches connect inputs to outputs

• Direct bus connection when switches are ON

• Ultra-low quiescent power (0.2 µA 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)

Product Description:

Pericom Semiconductor’s PI5C series of logic circuits are pro-

duced in the Company’s advanced 0.6 micron CMOS technology.

The PI5C16213 is a 24-bit bus-exchange switch designed with a

low ON resistance allowing connections to be made with minimal

propagation delay. This device operates as a 24-bit or a 12-bit bus

switch, which provides data exchanging between the four signal

ports via the data-select (S0-S2) terminals.
