20-Bit, 2-Port Bus Switch
Product Features:
Product Description:
•
•
•
•
The PI5C16210 is configured as 20-bit, 2-port bus switches
designed with a low ON resistance (5-Ohm) allowing inputs to be
connected directly to outputs. The bus switch creates no
additional propagational delay or additional ground bounce
noise. The switches are turned ON by the Bus Enable (xOE)
input signal.
Near-zero propagation delay
5-Ohm switches connect inputs to outputs
Direct bus connection when switches are ON
32X384 function with flow through pinout make board layout
easier
• Ultra-low quiescent power (0.5μW typical)
– ideally suited for notebook applications
• Industrial operating temperature: –40°C to +85°C
• Packaging (Pb-free and Green available):
– 48-pin 150-mil wide plastic BQSOP (B)
– 48-pin 173-mil wide plastic TVSOP (K)
– 48-pin 240-mil wide plastic TSSOP (A)
– 48-pin 300-mil wide plastic SSOP (V)
