PI5C34X484/P15C34X2484(25ohm) 40-Bit, 2-Port Bus Switch
PI5C34X484 PI5C34X2484 (25ohm)
40-Bit, 2-Port Bus Switch
Product Features
Near-zero propagation delay Low noise, 25 version (PI5C34X2484) 5ohm switches connect inputs to outputs (PI5C34X484) Direct bus connection when switches are ON Ultra-low quiescent power (0.2 ľA typical) Ideally suited for notebook applications Packages available: 96-pin Low Profile Fine Pitch Ball Grid Array (N96)
Product Description
Pericom Semiconductors PI5C series of logic circuits are produced using the Companys advanced submicron CMOS technology, achieving industry performance. The PI5C34X484 and PI5C34X2484 are 40-bit, 2-port bus switches 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. The PI5C34X2484 is designed with an internal 25ohm resistor reducing noise reflection in high-speed applications.
