24-Bit Bus Exchange Switch
Product Features
• Near-Zero propagation delay
• 5-ohm switches connect inputs to outputs
• Direct bus connection when switches are ON
• Ultra-low quiescent power (0.1µA 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)
Product Description
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).
