PI3C34X484
3.3V, High Bandwidth, Hot Insertion 40-Bit, 2-Port, Bus Switch
Product Features
Near-zero propagation delay 5-ohm switches connect inputs to outputs High Bandwidth (>200 MHz) Permits Hot Insertion. Rail-to-Rail, 3.3V Switching 5V I/O Tolerant Packages available: 96-pin Low Profile Fine Pitch Ball Grid Array (NB96)
Product Description
Pericom Semiconductors PI3C series of logic circuits are produced using the Companys advanced submicron CMOS technology, achieving industry leading performance. The PI3C34X484 is a 3.3 Volt, high-bandwidth 40-bit, 2-port bus switch designed with a low ON resistance 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 (BE) input signal. Eight bus enable signals are provided, one for each of the upper and lower five bits of the four 10-bit buses.
Applications
High Bandwidth Data switching Hot Docking
