24-Bit Bus Exchange Switch

ProductDescription

Pericom Semiconductor’s PI5C16212 is a 24-bit bus exchange

switches designed with a low On-Resistance allowing inputs to be

connected directly to outputs. This device operates as a 24-bit bus

switch or a 12-bit exchanger that provides data exchanging between

the four signal ports via the data select pins (S0-S2).

ProductFeatures

• Near-Zero propagation delay

• 5-ohm switches connect inputs to outputs

• Direct bus connection when switches are ON

• Ultra-low quiescent power (0.1µA typical)

– Ideally suited for notebook applications

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

• Packaging (Pb-free & Green available):

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

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

– 56-pin 173-mil wide plastic TVSOP (K)
